Cleanup & bugfixes of sloppy PHP script.

I have a custom wordpress plugin function in need of a cleanup. It is 171 lines of code in total. There are a couple of bugs in the code and a few sloppy coding mistakes that need cleaned up. You do not need Wordpress and Jigoshop in order to fix this but it is advised (get the latest versions of each). I will send you the code and we talk over skype if you win. Good luck
