On my Squidoo lens, I have lots of tips and resources for you. I don't know if you're considering residential or commercial cleaning. Really think about starting a small office cleaning business since that seems to be a fairly stable industry. Look for customers who have repeat clients themselves...like insurance agents, lawyers, accountants. They will be looking at cost savings, but also know they will have money coming in.
