One way to get cash for free is to collect scrap materials.  Copper, Aluminum, Paper… watch the market and determine what is valuable.  Copper is up right now, paper is down.

Where to get it?  —  Ask businesses (act professional, have a business card)
Supplies needed? — You would need a truck to haul materials.
Where to take it?  — Look in phone book under “Scrap metal” or “Recycling”
Also check the website ISRI.org for North America and BIR.org for Europe.

Aluminum cans average about 70 cents per pound and there are 32 cans per pound.   Don’t melt them at home, crush them maybe.   Look in the phone book under “Scrap metal” or “Recycling” to determine where to take them.
