I need an ordering system in the form of a joomla 1.5 component to help clients order my services. It should be customizable for all services from back end. Payment methods to be linked are: 1. Paypal 2. Moneybookers. 3. Alertpay 4. Swreg. Back end: admin should be able to customize the prices of the services depending on duration required to deliver and the amount of the service. Also, admin should be able to delete the orders from back end. also, admin should customize the payment details from back end. admin can view orders and message the clients through the system. Front end. customers should eb able to enter personal details (if never signed up) customers should be allowed to login if signed up before. then enter order details. then proceed to preview....allow to edit at this time. then proceed to pay... here allow to choose prefered payment method... then proceed... if not logged in... inform to login.....to manage order. Once logged in... see tabs ...............: 1. my orders 2. Order a new order, 3. Message admin for each order. 4. Pay unpaid orders. This means that the personal details should be able to be entered the joomla main user tables and then all the orders and order details should be entered in the order view admin side. KINDLY BID ON THIS PROJECT IF YOU UNDERSTAND JOOMLA 1.5 AND WHAT A WORKING EXTENSIBLE COMPONENT MEANS.
