I know a few people who make a pretty good living who started off with next to nothing and grew.

One of my friends has a business that for like $500 he goes to a house and spends the whole day just cleaning the out side of the house, front and back. He started with a second hand ladder, marketplace pressure washer and his Toyota Corolla. These days he works 6 days a week and is turning down work regularly.

It absolutely can be done, but the hustle is real.
