E-Commerce Site Needed

Hi, We need a programmer who is familiar with e-commerce sites. There will only be onme product. The order flow will be very straight forward, where users can choose how the product will look like, what kind of features will be included in the product. Some features will cost extra, so this will be added to the base price. There is also a section where users can type in personal notes what the product should include. The design of the site, the framework around the e-commerce software will be quite customices. It will not be like the default e-commerce shop look, mainly since there is only one product, but what will be heavily customised. Please make suggestion what e-commerce software would be good to use. If we can use os-commerce that would be good. But also, any other software will do. We rely on the programmers knowledge for that. Please make fair suggestion regarding the project fee and please show us some sample sites, which you or your company did. Thanks very much, and we look forward receiving your bids, Have a nice day, Cosmo
