Ebay API Scraper Tool

I need a software developer who knows the ebay API really well and can write some software. A developer who already has written a certified eBay application is very preferred. Here is what the software will do in 2 steps. I need a new application now and here are the specs. I need more competitor data. For example, I would like to provide a seller id for example: best_buy Once I provide this, I would like to know as much as I can about this seller including but not limited to: Every open ebay item number id they currently have open; anything else you can retrieve via the api. Lets say you provide me with a list ebay item id’s from this seller: 131223809662 I would then like a tool which I can put into a spreadsheet 100’s of thousands of auction ids, and I would like to retrieve all the data possible from the auction id including but not limited to: All item specifics, html description, all price info etc. finally, if this auction id includes parts compatibility, I would like to retrieve all that data also. Please let me know when you are available next and lets have a call to speak of this idea/proposal and how long it will take to put such a program together. I would also need a bid. I have researched the eBay API and all the above items are readily available for scraping and usage. I look forward to the bids and a conversation via phone or chat. Thank you. I would like this application in either a php/mysql format or .net/mssql format. Thank you.
