Wp e commerce custom payment gateway

Hello everyone. I am looking for a php coder to create for me a custom payment gateway for wp e commerce. I need a gateway that well accept credit cards where the customer enters in there info and then it sends it to the admin. I have a ssl certificate and can encrypt the info so to be secure. I have done some research and I know this is possible however when I tried to create via this link I kept getting errors and decided to out source for this. I am willing to compensate for your efforts. Just let me know. Thanks,
Aaron
