Re: Newsletter, brochure etc.
Definitely a good idea! Put a sign up form on your website and let people know you have a mailing list which gets them arty goodies in their inbox once a month. Google for more newsletter ideas besides a painting a month. People would probably love to read about your inspiration or how you made the piece etc etc. Putting prices up is always a hot topic: some people think it is a good idea, some don't. I generally don't put prices on my website but I do put them in newsletters as they go to people who specifically signed up to get more and deeper info. Up to you.
