Custom Open Cart extension needed for my package forwarding business.

*Before reading my proposal, please make sure to have an understanding of what "Opencart" and "VQMOD" are. Hello Freelancers, Here is what I want to accomplish ... I need the functionality that allows; [login to view URL] to receive packages belonging to clients, store those packages, and then allow clients to choose which packages to consolidate and which shipping method to use to forward those consolidated packages to the client's international address. I want this functionality to be built as a custom Opencart extension with VQMOD so that Opencart's core files are not altered. -- -- Here is more detail ... Since Opencart already has the functionality to administer client accounts, admin accounts, and process payments, we will not need to start from scratch. We'll just need to add the custom pages and make the necessary database modifications to operate them. *** It's probably best to now register a quick test account at [login to view URL] because the following notes closely relate to their client control panel. I've attached (FOUR) groups of hand-written notes which show the approximate pages that need to be added to the client's CP, the administrator's CP, the math calculations necessary to consolidate multiple packages, and miscellaneous notes ... - "[login to view URL]" - "[login to view URL]" - "[login to view URL]" - "Misc._notes" My hand-written notes/mock-ups show the workflow as a package arrives at my warehouse, is inventoried, and is then made available to my client to be consolidated with other packages, calculate shipping fees, accept my client's payment, and then reshipped to my client's international address according to my client's instructions. -- -- Here are a few more points ... I want to reproduce the simplified registration process of [login to view URL] where it initially only asks the client for their name, email address, and password to create an account ... But it then requires the client to provide the rest of their billing and shipping details before they are issued a mailbox number so that they can actually begin shipping packages to my warehouse. I will provide the following extension to be installed although it still may need to be modified to operate in the way that I just described: [login to view URL] When requesting shipping rates from carriers, we'll need to integrate with my existing account at: [login to view URL] When requesting tracking information for shipped packages, we'll need to integrate with my existing account at: [login to view URL] For payment processing, I would like to use [login to view URL] and Stripe.com. I will provide this [login to view URL] extension to be installed: [login to view URL] For a FAQ system, I will provide this extension to be installed: [login to view URL] I'll need a specific front-end page that allows clients to calculate shipping to their destination. Here is an example: [login to view URL] -- -- I am ready to begin immediately. Let's talk.
