Any Ideas on how to find local people who will let you camp/very low rent land to camp on?

I own a car but it cant leave my city because I blew the front headgasket so I cant drive it longer than 30 mins. For this reason I can't drive 40mins to a hour to the next city over that has tons of greet camp sites that are for free. Also Id like to keep my job because even know the pay isnt the highest it gives me insurance.

So I need to find someone locally who is willing to let me pay them 50 to 100$ (or free labor) a month to let me camp out in their backyard or extra acra. Any ideas beside walking up to doors and asking.

Are there any campgrounds near where you work?

If so I would suggest talking to the manager about letting you camp there in exchange for work.  They have all kinds of opportunities for people to do in exchange for a campsite.

Lawn maintenance, cleaning bathhouses, taking campers to their campsites, etc.

Churches and community service clubs are a good way to connect with lots of people and get the word out.
