Build a price comparison site

Descripción del proyecto:
Hi , I am looking to build a comparison site. Along the lines of Gocompare.com/Comparethemarket.com . Simular lay out and functionality. It will be based on one subject. Comparing everything to do with that subject. It will need rss feeds and affiliate links to all golf related products and sites . I would like a function where i could upload and sell my own product should i choose too. It wants to be PhP with a mysql database.I would also like it to incorporate silo structure where possible. I want it to update automatically . I already have the Domain and i've a graphic designer designing me a logo.

I know this is totally running before i can walk but i would like to get into the US and Japanese markets too. Compare all prices in there countries. Thinking big.

Any more information need just ask. This will be an ongoing project with more money to be earned than one set fee.

Look forward to hearing from you.

James
