Might I also add the following:
Introduce yourself as an artist to those you meet and always have a business card handy and hand them out without hesitation. Be sure your business card has one of your works of art on it.
Have a web portfolio- and be sure every image on it has a legible watermark with your name and copyright on it. (Orphan works is not dead)
Attend local shows and network with local artists.
Always have a portfolio in your car- you never know when an introduction will turn into “you know my brother is opening a new club downtown….”
One important thing to remember as an artist is that nobody is going to promote you- you have to be confident in yourself and promote yourself.
