Twofish + whirlpool hash

Hi to all. I know, Hashcat support Whirlpool and Twofish, but I can not use it for my task. I have the source code, written in C ++, but its speed is very slow, because it uses only CPU. I need to find a working solution for AMD Radeon (HD 7970) to decrypt the hash that was created using these cryptographic functions. Can anybody advise me where I can find programmer who could port this source code to AMD Radeon for a good reward?
P.S. If my topic violates the rules, I am ready to remove it. Thanks beforehand.
