There is a company- Google it- in Atlanta called International Catastrophe Solutions. It started as a tiny family carpet cleaning business. Seriously... go to their website and see what they do NOW, lol... if you have the drive and the brains, you can take a maintenance business a LONG way. But never let yourself get distracted. If you are self-employed, it's on YOUR shoulders to be sales, management, bookkeeping, human resources (yup- you don't have anyone threatening to fire you for coming in hung over; you just CAN'T DO IT) and labor. Owning your own business is rewarding IF you bust ass and keep your goal in mind.

Where do you intend to get start-up capital?
