Most micro small businesses have 1-10 computers and they get most of their IT support from internal gurus. If the guru can't fix it then they move on to help lines that charge $1.99 or $2.99 a minute. They will also search vendor websites and forums to find the answers to their questions so that they can do everything on their own.
Volunteers are another way that micro small businesses get their IT support. They usually have a family member who can fix their IT problems. He or she may not be able to get there for a few days but since they work for free the micro small business doesn't really care.
Competing with free is tough but you can use these micro small businesses as stepping stones. You might want to start out working with a few of these companies as you build your way up to larger sweet spot businesses.
