cheapest car rental

My boyfriend and I are considering a trip from Chicago to New Jersey and back with stops along the way. I would like to know how to get the best rate on a rental car with unlimited mileage to possibly do this in.

This is a commercial we made for Thrifty Car Rental! lol had a great time!

I have no job. So I thought I could start a Car Rental Business. I live in Ontario. How much would it cost for the car, insurance and other stuff?

Thanks in Advance
