I would like to make a on-line psychological counseling using wordpress and e-commerce. The idea is: the patient contacts with psychologist via contact form and when he (or she) press "send" button he (or she) should be take to site where he (or she ;)) can pay for the service. I was thinking about using a e-commerce plug-in (because of payments) and pressing the "send" button will add one item of "service" in to the cart and go directly to payment site. But i don't know how to do it. Will somebody be able to help me or bring me closer to solution of my problem?
