I am a web designer working on a project for a client of mine. The client has a need to integrate Paypal's Website Payments Pro to process their credit card payments.
I am not awfully familiar with using APIs and need an expert to help me integrate the gateway. I can explain how the e-commerce software works (it was developed in-house) and try to be as helpful as possible with pointing you in the direction of relevant code, but I need someone else to write the integration!
There is a similar payment gateway set up already that may or may not be useful (Eway).
Deadline is quite tight and there will be lots of ongoing work for the right person.
