Become a dog walker if you live in an area where they are in demand. You can walk dogs for people who own dogs but who are too busy to walk them.

If you like (or think you'd like) buying and selling houses, and you're handy, you might profit by flipping homes -- buying, fixing them up, and then selling for more than they cost you. This can require a lot of skill, to repair or renovate the homes, or it can require a lot of money, if you'll be hiring others to do the work. Still, this activity can generate a lot of extra moolah on the side.
