What is the best outsourcing company for building a vendor based eCommerce site on a very small budget?

I am looking into building a vendor based ecommerce site on a very tight budget. I have received offers from some companies like BRsofttech.com which makes "readymade" websites and outsource2india.com which is a more traditional outsourcing firm but a lot of their work seems second rate (I'm not really surprised). What is the best vendor based website creator for people working on a really really small budget? Or is there a better way to go about creating such a site? I know this is a really specific question but any advice would be great. Thanks!
