I would like to hire a freelancer to create a site like [url removed, login to view], it is a site hosted in Hong Kong but you can use google translate to your language to get an idea of how it works.
It is basically a price comparison and review site, it allows users or merchant to submit prices for products (currently that site only focus on electronics and computers but we want the scalability to add more categories).
Let's say a user bought an iphone4 today and want to share his price on our site, he/she can visit our site, browse or search for iphone4 and tel us how much and where he bought this gadget. So when other users come in they know where they can get the best bargain, if it is a local store and it is close he/she can simply get it locally; if not he/she can compare online stores too. The idea is a user can come to our site to find their best deal (online or offline merchant) and all data are shared by REAL users or merchants. Merchants can also use our site as a platform to promote their products or stores - for instance I have some iphone4 that I want to get rid of I can "share" my price online so users can compare my promotional prices with other merchants.
The project should contain a site-front and admin backend for managing users, merchants, categories, products, promotions, notifications, and the scalability to extend the site.
