Amazon Dropshipping - Supplier Inventory/Price Checking app -- 2

Hi I want you to build a price and inventory tracker for the sites. I will be providing you laravel saas boilerplate which include most of the thing so you need to focus on script of scrapping prices and other. 1. Single Standalone Script in either PHP or Python 2. It will fetch the product and find the pricing from the url you saved in the DB 3. If price found and the price differ by $2 from the previous price then it will update the latest price in the same table 4. Also it will update the Price on Amazon whose product matched with ASIN 5. In case price not found then it will set Out of Stock and nothing is update on Amazon 5. Script will Run every 30 mins 6. IP rotation and captcha solving so scrapping will not be blocked. - User can register to my app and choose plan based on their leads. I want 3 plans {1st Regular and it will allow max 100 leads, Silver - 500 leads, Golden 1000) - and they should have a page where they can connect their amazon store using mws api. - you will have to create the db and assign it correctly cause I don't have any other developer. # I want you to build a xpath price grabber and a text string finder on item page code because that way I can add as many suppliers sites (marketplace sites I want) Thank you very much
