We occasionally do what they call "flip" a car. Buy a car cheap, fixed it and resell it for a profit. But that can be dangerous money wise if you don't know alot about cars. Hubby knows alot so that helps. We try to flip at least 1 car a year but sometimes 2. And we make anywhere from 200 - 500 per flip. :)
oh, with that being said I think the other person had a great idea. Boarding pets is a decent job if you put the word out. Lots of people would prefer someone who actually has the pet living in the house with them instead of a "cell" when boarding. :) Just a thought.
