Small business development center through community college:
Through Maricopa community colleges:
The small business development center offers free business advising. You can get one on one mentorship with a business analyst on everything from learning how to file taxes, an LLC, etc, to developing a business plan and social media marketing. They also offer classes for cheap. I happen to teach web design classes through them.. but it's a great free resource for small businesses, might be something to add to the business resources on AZ artisans site.
