I saw today that contest was deleted... but I am still interested to buy the code from you. New project is at address [url removed, login to view]
As I suggested before you bid on the project and make a milestone payment of 300$. That way I can pay you for the code and if everything is ok, I will release the final 100$.
If for any reason you don't want to finish the project please tell me so I can hire some other freelancer.
