Creative way to make money offline

Hello all,

So in trying to make some extra money for a vacation I am taking some additional jobs.

One job that is only 1.5 to 2 hours per night is cleaning offices. Its flexible, easy and pays above minimum wage.

Other option to bring in more money that dont require extensive work or time include:

Donating plasma
Babysitting
Holiday retail jobs
dog walking
Coupon clipping
