PHP module for shopping cart

We are looking for PHP developers that are specialized in e-commerce and shopping cart systems. The project involves integrating our PHP Proactive Sales Module into e-commerce software like web shops, shopping carts etc. The module description and how it can be integrated is available on our web site if you search the net for sevana oy. There you can also find its online demo. The idea of the module is that we analyze list of purchase transactions (what customers buy as a single purchase is: track1, track23, track76, ..., track17) and search for associations within purchases digging out buying behaviour of different type of customers. Thus we have two results: 1. we can say f.e. that if somebody buys track23, track67 and track 44 then he will also buy track 17, and furthermore one can predict that if somebody buys track23, track67, track44 then he would also like to listen to track86. All of this comes from analyzing purchase transactions made by other customers. This can be done once a day f.e. or even live for a single customer while he makes his purchases on the site. This leads to the following scenario: an online customer buys one track, the script checks what other tracks usually come with this one and your online shopping cart displays links to these tracks f.e. on the right panel attracking customer's attention. When the customer buys second track (not necesserely from the right panel) the procedure repeats and so forth till he stops buying or exceeds "the knowledge" hidden in the purchase transaction data. This results to customers easier finding tracks of their interest and increasing purchases (they get links to tracks they are interested in, because the analysis is based on the purchases of the customers with the same taste). ## 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.
