Hiring programmer to modify Python code for different n,k parameters

Prohashing is currently looking to hire someone to modify some existing Python code taken from the ZCash repository to function with the Zelcash <125,4> parameters. This code correctly validates submitted hashes for <200,9> ZCash and for <144,5> Bitcoin Gold, but returns that <125,4> Zelcash hashes generated by gminer are invalid.

The programmer needs to determine what makes this code invalid for the <125,4> parameters, but not for other parameters, and submit a fix to us. The job may be as simple as changing one character, or it could be as complex as rewriting some portions. Reply with a bid if you’re interested.
