Hire a Web Scraping Specialist

Hello I have 4 broad objectives I'd like to achieve. 1st I'd like to be able to enter a list of Amazon ASINs and be able to scrape a report from Amazon. Id like to be able to generate a report first showing on an ASIN level who (amazon, what 3rd party seller) is selling a specific ASIN and at what price. I'd then like to be able to compare it to our MAP price standard and identify sellers Amazon or 3rd Party that are below our price standard and take a screen shot, and tie it to a report of exceptions. I'd like to know when that violation was first noted and the date the price was changed or the seller removed the item. 2nd I'd like to scrape google shopping to identify the same data points as with amazon and generate the same exception reports with screenshots, and track violations. 3rd I'd like a framework built to scrape specific websites. I understand that each website will require its own programming. I'd like to start with 5-10 websites as a trial, then establish a fixed price to add additional sites in the future. 4th (and I know this is the hardest) I'd like to explore ways to crawl the web looking for websites selling our products we may not be aware of, so we can ultimately fold them into step 3. I'd like to pay a fixed price for all 4 of these objectives, on a milestone basis. then negotiate a long term hourly rate for maintenance. The app must run in a headless ubunutu server environment. The screenshots must be saved to an s3 bucket. The data should be saved into a database sql, postgres, etc.... This needs to be a durable solution, not one that works one day and breaks the next, while we are willing to pay for long-term maintenance we need a delivered, well documented product that works. I'd like to be able to temporarily remove an item from enforcement activities if we have a sale and grant a MAP waiver, and I'd like to be able to track violations per offender. There needs to be logic on the log file to be able to tell that seller A violated monday, tuesday and friday, and seller B violated monday-friday. Therefore seller a had 2 violations 1 lasting 2 days and another 1 day, whereas seller B had 1 violation lasting 5 days. We will ultimately want to host our production server.
