I have to agree with the ones who are encouraging you to try Etsy, before investing any serious money into this.
About the website, I've designed several (personal) websites and they are NOT HARD to do. You don't need to be an expert, to do your own. There are programs available, which help a lot!
Also, beware of companies that claim they'll help 'get your site to the top of the listings' because some of those are nothing but scams. I used to have a relative, who worked for one (he may still work there but is no longer a relative, so I don't keep up with him). I won't mention the name of the company but it's starting to receive more and more complaints, from customers who've been scammed.
