I see you chose to build it at Homestead! I think you made a good choice; that's where I built my first two websites and let me tell you that it is a WHOLE LOT EASIER than using e-commerce software and trying to learn CSS & HTML.
If you don't understand that last sentence, don't worry, you don't need to, because you're at Homestead!
I believe that Homestead interfaces with PayPal, so be sure to set that up for your items. When I first began my site, I didn't allow for payment online; shoppers had to mail in their orders. That was a big mistake, as I found out later when I added the ability to pay online. Sales immediately went up 30%. I was shocked!
'Course I started building my first site back in the medieval times. Like in 2003. Ancient history now...
Best of luck to you!
