Auction / retail store

Need program and front-end to run auction and a retail store. ( example would be [login to view URL] ) This would include login to site, email to subscribers etc. Program would have to communicate with shopping cart. The only none straight forward part is, I would like to have a certain type of client receive discounts on other parts of site. Could be a simple a setting bit flag, that's up to you. Will disclose entire package to bidders. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Should be platform generic: But the current platform is Linux 2.4.20-19.7 running apache. Have the usual cgi,perl, mysql, php, sendmail etc...
