eBay > Amazon Item search

I require an API than will communicate with both eBay and Amazon APIs. The API will expose methods that will interface with the below. Ultimately this will provide the basis for web services, but initially, this is fine without front end. Phase 1 is to be completed as soon as possible. I have provided some good details below. Please only follow up if you a) Have specific questions about the implementation (I am not entertaining blind offers without full understanding) b) Can communicate proficiently in English. c) Are confident that you can achieve the following, in the technologies I’ve requested. Phase 1a: eBay Item Search Ability to search a given eBay username, to quickly retrieve currently item, item ID, sold count, and watched count. Search to be written in Node JS using the eBay API. getSellerList provides all the functionality. Search should be filtered to return in JSON format. For now, this will be just for [login to view URL] site, but ability to support others in future. The search can be accept parameter for how far back to search (last 5, 15, 30, 60 days). Search can accept parameter for minimum sold count (i.e. more than 2) Phase 1b: Amazon Matching As each item is retrieved, the system will then search amazon API (again in Node JS) so very fast. Results will be retrieved, then populated into JSON. Dispatch events as the search progresses. Search will be FAST. Search will have no limit (but can be limited via parameter) Item search result will be populated with: If item has provided an exact match against Amazon using the eBay title (or significantly close enough to be a math) Link to the amazon item should there be a match, link to the amazon page search results if not. eBay sellers price Amazon price (if matched) url to thumbnail image of each listing (if matched) eBay Sold Count eBay Watch Count Amazon ASIN number Phase 2a: Storage No SQL Server, hosted on provided AWS box. When selected, a user can be saved on the system. This will save the seller, along with a list of their item IDs Subsequent searches will highlight the sellers new items. Phase 3: Display Yes, you guessed it. This needs to have controls and web interface. For now this is in the future, but all aspects need to have this in consideration.
