Hi.

My friend asked me to implement a TatraPay payment method to his ZenCart eshop. I have never done anything like it before. I have a quite detailed manual from the bank about how to do it, but the process requier a lot of coding, including calculating various hashes, cyphering and other various stuff (mainly PHP) which I am not too familiar with.
Is there any helpful soul that is willing to sacrifice some time to help me succeed? I can translate the manual to english. There are also some resources for osCommerce, which might be helpful too (but not to me though).
I will appreciate any effort and cooperation and since it is not a matter of "copy-paste this and that", here is my ICQ number for faster and more comfortable communication: 220218226.

Thank you in advance for any useful advice :)
