I'm looking for a programmer who can create a site like terapeak.com

http://www.terapeak.com/

Retrieves listing and sale information from eBay, then generates reports on the most profitable sales and categories, the most profitable days of the week, returning buyers and more.

There are mainly 4 features on the site. I would like you to create two of them.

1.Product Research
2.What's Hot

It can be translated the complete interface to any languages
