online shop

I need some advices and guidelines on how to set up an online shop. I own a server(Fedora 6 OS with Apache) and I'm ready to build my website. My question is, what kind of development tools(programming languages) that are commonly used to set up the features below? Are there any other options available? What are the merits and demerits of these options? (1) shopping cart (2) email system(eg email order notification) (3) credit card processing (4) product catalog (5) product search (6) user registration (7) order processing ## 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. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform linux
