Custom development on PHP shopping cart

We are looking for PHP developers that can help us modify PHP based shopping cart software. The ecommerce site deals with different items. It has to tie in with other online retailers like [login to view URL], [login to view URL] etc. Thus we need the site to be able to switch from its internal shopping cart facility to direct users to the various retail websites to make their purchase. To have an idea of what we are looking for, visit [login to view URL] and try to make a product purchase. So in summary, we need: * Extended vendor information e.g. vendor member ID * Extended product details e.g. product sku for the respective vendors that sells the product * Switch field in config page to either use internal cart facility or the custom setup as above. In other words, we'll like to keep the cart's functionality ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
