How can one set up a business with a skill of painting houses?

[King Belieal]

There are people that have learned the skills of painting houses and they are very good at it. Is there a way they can use that skill to start a business? How do they go about setting up a business around this their painting skills?

In fact that business seems very uncompetitive here in my location. That is because the business is being done by only a few number of people here.
