Online Pharmacy

I am looking to get an mail order pharmacy site designed like [login to view URL] or www.medsviacanada.com. The site must be easy to use and navigate. Most of the orders will be routed to pharmacies in India, Great Britain, Canada, Turkey etc.. The system must be an easily modifiable store with ecommerce, front and back ends, and four password protected sections: Administrator, User, Supplier and Affiliates. My target customers are in all countries but mainly the USA without insurance or high deductables. The system must be have: (1) Admin Panel that allows addition of new drug names and prices to store. (2) Easy changing of drug names and retail prices (3) Easy entry and updating of order process, fund receipt, order routing and mailing. (4) Capability for any format of Doctor's prescription internet upload or fax database storage. (5) Database of customer demographic (name, address, phone, email, allergies, medical problems etc...) (6) Affiliate section I also seek some sort of maintenance agreement, which includes changes and updates, search engine optimization, and other webmaster tasks that may arise. Thank you.
