I want to sell a service online. I already own my basic domain and have hosting for it through godaddy. I want to sell a service through my website. However, I don't want people to be redirected to a third party website in order to pay for their service. How do I go about doing this? It is really only 1 service and no "cart" is really required. It will just be 1 form that they have to fill out and 1 flat price.
