I need you to program an order receiving system like the one in this site for my similar website. [login to view URL] I need the database order system with a client area just like in the given site. The order system you design, you will then install in my two websites only serious bidders who have done this before are encouraged to bid. therefore I will want to see your previous work. do not bid with pre-written messages as you will not be considered
