I second that builderspot is super easy. It is $20 a month and has shopping cart built in. The only thing wrong with it is that it doesn't automatically keep track of inventory but unless you are a super-busy and successful site, this isn't a big deal.
I knew NOTHING when started and I set up my site in 15 minutes. It wasn't as nice as it is NOW, but functioning nonetheless. There are people there to help when you ask questions and often it only takes an hour or so for them to get back to you and often they just fix the problem for you and tell you how they did it. Emily, who works there, has even fixed cosmetic things for me for free, using her own personal software!
(Still have lots of work left to do, I know.)
The best thing about is that they have collected info on the easiest and free thumbnail programs and the best place for info on this and that and they set up deals with other companies like authorize.net (I think that is what it is called.) to set up credit card authorization for little money. The have an easy to read list of the best resources.
As soon as you make a change to your site, you see it right away. You can try it for free, and I highly recommend it. I have turned a few people onto it. To see some sites that I, knowing NOTHING about this stuff, have done, visit
www.tickled-pink-designs.com (my site) and
www.kboychuk.com (my friend's site). I know they aren't amazing or anything but they are pleasing to look at, easy to read and easy to navigate.
Best of luck!
Natasha.
