The title says it all: I need similar iStockPhoto "Credit" based payment system for my site.
If you are familiar with the popular istockphoto site you know they use a credit based system for payments. You purchase credits using paypal or credit card, then you use the credits to purchase their photos and then you refill the credits when you run out.
I want this same credit based system for my site. Please PBM your plan of action and solution. Serious experienced programmer only.
Please start your message with "flash" so we can know you read the project and not blind bidding. Thank you
