I would recommend either Weebly or Wix (in that order) I have supported sole traders to use both.
Weebly is a nice 'drop and drag' platform with loads of templates, good tech support from them as well. I believe the starter account with Weebly enables you to display 10 products for e-commerce and you can also connect your domain name properly (I don't work for them honest)
But to cut down costs have you thought of creating a portfolio website, general info, events you are at etc, then redirecting and having your shop on something like Etsy, Folksy, Not on the High Street... your audience (sorry I am assuming your audience goes here) is already gathered in those places and they often show the 'other customers also like this item' where you could potentially show up... This way you don't have to manage the extra e-commerce stuff as a pre made site like Etsy etc, does it all for you of course they do take a small percentage but I think it is Etsy where you can pay £20 per month to list as much as you want and you keep all profits.
Alternatively a dedicated e-commerce builder I have used is Create.net that is around £110 per year. Lovely site, I believe easy to navigate round and now even easier to use (the when I first used it two years ago) with good tech support and guidance.
Happy to help if you want any guidance or just another opinion
*Good Luck*
