Classipress payment system

I need Classipress configured to accept different levels of payment. This is a plug in for Word Press and is a system for offering classified advertisements to customers.

There is a payment process encoded in the plug in but we need to expand it to offer different levels of payment for different styles of advertisement. This will require some good PHP knowledge and familiarity with WordPress. We can provide the original Classipress files. Rapid completion required if possible.

Please feel free to ask any questions.
