Hello! I am a professional programmer with many years of web scraping experience using Python. I have read your project description, and I can create the program to automate the process of collecting a link, creating and posting to pdf, and saving to Dropbox. To do so, I will use the libraries Requests (for web automation tools), BeautifulSoup (for parsing html), and Selenium (for working with AJAX and Javascript, if necessary). Please contact me so we may speak further and so I can send files. Thank you for your consideration.
