Hello, I specialize in online checkout/processing. I have created specialized checkout processes for many small online shops and have worked side by side with developers from many highly rated 3rd party processesors such PayPal, iBill, SafeCharge, FirstWebBill, Netbilling, and AuthorizeNet. I can create a simple or very in depth 'Customization Wizard' for you needs in very little time depending on your needs. Please do not hesitate to contact me.
