Hi, I have my own website purchased from create.net. It costs me £9.99 a month and was quite easy to do, I have six shop sections, a blog, links etc on there. It also uploads and links to facebook.
I also have two shops on Etsy and one on Folksy (british equivalent to Etsy).
I am also on WowThankYou, you need to submit your website and some picture of what you make then wait to see if you have been accepted (they look at the quality of your items, your wording and presentation).
With your own website you have to get it seen by the search engines and try and make page one on google as people rarely go past page one when they search for things. You need to do your seo, submit to search engines, get links, look at adwords and adsense.
Etsy is US based and is huge, you need quite a lot in your shop and need to make your photos exceptional. Etsy to me is quite a cheap selling platform but make sure you use the correct keywords and that your postage charges are correct (I have sold this month to UK, US, Spain, Portugal, Argentina and Hungary).
Folksy is slightly dearer than Etsy to list but would probably be a good starting point for you then you could see how the market reacts to your products, have a read through www.folksy.com.
I only list on eBay from Oct to Jan as I find the fixed price fees prohibitive and the eBay ethos not conducive to the handmade market.
Have you looked at a payvement store on Facebook?
