integration of new payment system

I'm looking for someone who can help me with the integration of a payment system. I have now a working version but they have upgrade their system and now it doesn't work. The new system is almost the same like the old one.

You can analyse a problem very fast and messages like 'headers Cannot modify header information - headers already sent by' are not strange for you.

I have a complete english manual in pdf for you but I think when you are smart you will understand what is wrong by error.

Your bid is not your final bid. When you need to do additional work then I will pay you for it. I'm looking for a smart guy (or woman) who can analyse the problem and fix it. And can start at this moment.

You are working in a simulation mode.
