I need help with putting a shopping cart on my website?

Christina A asked:


I created a website in my Dreamweaver program. I have a host, domain, and the design. What I need help with is putting a shopping cart on the site. I really don’t want to use PayPal. I plan on getting a merchant account with a credit card processing company as well as a business bank account. A credit card processing company I am looking at offers free software (gateway software), and I’m not sure how this works with my site. Is there anybody here that has a website with a payment system on their site that can explain the process? Does the software give me some kind of code that will corrispond with my site. I’m not selling products. I’m selling ad space and a local directory. So when people want to advertise on my site, they’ll pay an ad fee. Kind of like classifieds. I want the customer to see their ad and the fee they’re being charged. I also created an order form and I would like to understand how I can incorporate a shopping cart w/ the form.
Can anyone help? Thanks.
