Google Merchant/ Spreadsheet Gadget Plugin

Here's another plugin idea. I've posted it to a few developers and seen some interest, but wanted to see if anyone else was keen on this idea:

I'm looking for the integration of a google merchant account with the google gadget that allows you to create a shopping cart through a spreadsheet. More information can be found here:

Ideally, the interace would allow a user to create a new merchant account, important the spreadsheet, and then do their own customization from within a window in the wpmu admin area.

I'm actually looking for a developer who can handle that, or tell me if it's even possible, and then give me a quote on price. Timeline is to get it up and running sometime before the end of the year - the sooner the better.

Thanks for your time and response. If anyone could also recommend someone, that would also be appreciated.
