Amazon / Ebay Product Research and Comparison Tool and More

OK. A few Conditions to make perfectly clear before we start with the proposal. 1. I am paying for a software that will ultimately be owned by me in it's entirety. You don't retain any copyright to the program/source code after each milestone payment. Meaning I can use it how I like, even for resale if I end up choosing to do so. 2. All source code must be accessible during each stage of the project, so I can analyze and compile them on my side to make sure progress is being met, and you are not only using front end/user interface code. 3. The program must run as a standalone desktop program on the computer without using back end code on servers. Meaning it is not reliant on anything other than itself to work (and the websites Amazon and eBay not changing). Project: Each step will be discussed more in depth before starting, to make sure you fully understand what is required. 1. Amazon Product Research Tool This is the easiest part of the project. This project will require to scrape details of the product page. User input data for calculations. And also scrape Amazon Fee Calculator fees after putting in the ASIN. I have a draft example spreadsheet I have made which the program columns should look like. It is missing a few small scraping things I want, but this is generally the idea of how it should be. I've added it to this. Also stock levels of competitors. This can be done by putting a request for 999 of their item, and getting the number Amazon returns. 2. Amazon And Ebay Comparison I should be able to search a keyword or seller ID on Amazon. And it will get the matching results on eBay. It does this by getting using exact title match on eBay from Amazon, and then scraping various details, and doing calculations. It will also do part of an exact description match, and give a Yes or No in a column. You should also be able to do this backwards. If I type in a keyword or seller ID, I should be able to see the same eBay products on Amazon. 3. Saved Results, Automatic Price Checking/Rescraping, Exporting, and Autolister, Graphs, Product History/Data Analyse a. Once I have found the results I want in either of the two research tools. I will then be able to save these results in the program. The results will always be there when the program opens and closes. These are products I want to keep my eye on. b. On this page of the program, I should be able to, by clicking a button, or by setting a timer, automatically update the scraping data and calculations for that product. Basically the same thing as the first tools did, but a refresh/update for saved results. c. We will also implement an exporting to CSV file option here. d. We will also implement an upload to eBay option here. (Auto lister) e. Graphs will track changes in scrapped data. For example prices, stock levels of competitors, just plotting scraped data that the program already gets. 4. Support for the program for 3 months. This is also an easy part of the project. You do not have to add any new features. You just have to fix any problems or bugs with the program that may crop up within 3 months after you finish it. For example if the program works perfectly for 3 months after you finish it, then you will need to do nothing.
