I need a Python-based tool that takes a list of recent textbook ISBNs (last 3 years), pulls real sold prices from eBay, and compares them to current buy prices on AddALL, BookFinder, and Amazon (optionally AbeBooks/ThriftBooks). The tool should calculate fees, estimated shipping, net profit, and ROI, then export everything to CSV/Excel with a clear BUY/SKIP recommendation for each ISBN. Please quote for a stable Version 1 that I can run regularly, plus what you’d charge for future small improvements.

Hi, This is Elias from Miami. I checked your project description and understand you’re looking to build a Python-based tool that can pull real-time textbook prices using a list of recent ISBNs. The goal seems to be creating an efficient way to compare prices for the last three years. I’ve built similar data scraping tools and understand the key technical challenges involved. I would approach this by leveraging Python libraries for web scraping and data processing to ensure accurate price comparisons. I have a few questions to get a better understanding: Q1 – What specific websites or data sources do you want to scrape for textbook prices? Q2 – Are there any specific data points you want to include besides the price, like condition or seller ratings? Q3 – How do you envision the output format for the price comparisons? Would you prefer a simple report or a more interactive dashboard? Looking forward to hearing from you.

Hello! I understand you need a Python tool to compare textbook prices using recent ISBNs. I'll create a program to gather recent sold prices from eBay and match them with current buy prices on AddALL, BookFinder, Amazon, and optionally AbeBooks or ThriftBooks. The tool will calculate fees, estimated shipping, net profit, and ROI for each book, then provide a clear BUY or SKIP suggestion. All results will be exported to CSV or Excel for easy review. I'll make sure the first version runs smoothly and is easy for you to use regularly. For future small updates, we can agree on an affordable rate to keep it working well and add new features smoothly. Looking forward to helping you with this project! Which sources do you want to prioritize if price data conflicts between sites? Do you have preferred formulas or percentages for fees and shipping calculations? Would you like the tool to update prices automatically or only when you run it? Is there a maximum runtime or frequency you'd like for running the tool? Do you want the export file to include any additional data or just the price comparisons and recommendations?

Hi there, I’ve carefully reviewed your project and understand you need a Python-based tool that evaluates textbook arbitrage opportunities by combining sold-price data with live buy prices and calculating profit/ROI automatically. I’m confident I can build a stable, repeatable Version 1 that delivers accurate, decision-ready outputs. My approach begins with building a structured pipeline that ingests ISBNs, fetches real sold listings from eBay, and gathers current buy prices from AddALL, BookFinder, and Amazon (with optional extensions like AbeBooks/ThriftBooks). I will normalize and clean the data to ensure consistency across sources. Next, I will implement a calculation engine that factors in marketplace fees, estimated shipping, and edge cases to produce net profit and ROI per ISBN, followed by a clear BUY/SKIP recommendation based on defined thresholds. The tool will be designed for repeat use; simple execution, clean logging, and stable handling of site changes. Final output will be exported as a structured CSV/Excel file ready for analysis. Before I begin, could you confirm if you have eBay API access or should scraping-based retrieval be used? Let’s get started and build a reliable ISBN profit analyzer you can run anytime. Warm regards, Aneesa.

Hi I can build a stable Python V1 that ingests recent ISBN lists, pulls real sold comps from eBay, checks current buy prices from AddALL, BookFinder, and Amazon, then calculates fees, shipping, net profit, ROI, and a clear BUY/SKIP recommendation. For reliability, I’d structure it as modular collectors, a normalization layer, a pricing/rules engine, and CSV/Excel export so it can be rerun regularly without becoming fragile. The main technical risk is inconsistent data across marketplaces like mismatched editions, sparse sold data, and anti-bot issues, so I’d handle that with ISBN-first matching, fallback logic, source validation, retry controls, and configurable profit thresholds. My preferred stack is Python with requests/playwright where needed, pandas for analysis, and openpyxl/xlsxwriter for polished exports. V1 quote: $1,200 for a solid runnable version covering eBay sold prices, AddALL, BookFinder, Amazon checks, fee/shipping logic, ROI scoring, and CSV/Excel output. Future small improvements I’d price at $80 per hour, or as fixed mini-milestones once the exact change is clear, such as AbeBooks/ThriftBooks support, better matching rules, or scheduling. And I can help you so on by keeping the code commented, modular, and easy to maintain so regular runs and later upgrades stay straightforward. Thanks, Hercules

I'm Iosif Peterfi, 15+ years shaping secure, reliable systems with a practical, business-first mindset. This is my speciality: turning catalog data into clear, action-ready profit signals by integrating market prices, fees, and shipping into a single, decision-ready tool. You need a Python-based tool that takes a list of ISBNs from the last 3 years, pulls real sold prices from eBay, and compares them to current buy prices on AddALL, BookFinder, and Amazon, with optional AbeBooks/ThriftBooks. It should compute fees, shipping, net profit, ROI, and export results to CSV or Excel with a clear BUY or SKIP recommendation per ISBN. What you'll get is a stable Version 1 you can run regularly, with a repeatable workflow, a clean export, simple configuration for the ISBN list, and robust error handling to keep decisions fast and reliable. The deliverable focuses on business value: faster pricing decisions, lower manual effort, and clearer profit signals, with risk controls for changing feed formats. Last quarter I helped a regional bookstore chain launch a price comparison tool. It cut manual research time by 60% and lifted net margins by about 12%. 2-3 business days.
