Need a shopping cart - help desk system. Can be unique or customized script similar to photo selling cart sites.
User will pay for a monthly membership fee in which they get a fixed amount of credits to go towards available services. Each month unused credits will be wiped out and a new allotment filled.
Need help desk type environment for users to choose from available services and make notes on details needed. Credits will then be deducted from their account for that particular service.
Project is then routed to team leader who dispatches job to individual service provider.
Should be a similar script out there for customization.
Needs to integrate with 1shopping cart for payment processing and affiliate commission.
