Also, quick advice on paintings, there is a market it's like you said, you just need to be FOUND.
You need to use all of the "goods" Social Media, blogging, SEO, etc.
I know it's tough to learn it though, so I'd honestly just say signup for the newsletter, b/c It'll be an easy source to learn from
I'll be running an internet traffic mini-course in the near future, if you'd be interested.
