In these modern times a lot of ways that folks used to make money have been forgotten about.
Mowing yards.Now I can tell ya most folks are cheap,but 3 or 4 ya might start making a little.Requires a mower and weed eater.
Trapping in season probably best if you have a friend who can teach you.You can learn from books or even internet.Does require equipment.
Hunting for ginseng,mushrooms,etc.Requires sharp eyes and knowledge of subject being hunted.
Yard sales or swap meets. I knew a lady who went to yard sales but good stuff cheap and resold at her yard sales for a profit.
If yer the type who ain't embarrassed to pull something out of the trash you would be surprised at all the things that are thrown out that still work.Pick em up and sell em.Requires car and no shame in yer game.
Hauling many ways to do this,figure out what will work in your area.Requires a truck and strong back.
Picking up scrap metal.Copper,brass,aluminum,a/c units are the money makers.Sheet metal refrigs stoves etc takes a lot to make money.Car or truck and a few tools.
Selling stuff on ebay,craigslist,etc.I used to know a dude that bought wrecked cars and sold the parts.He made a lot of money from parts way more than whole car.Requires tools.
Some folks where I live hire dog walkers/nannies.Yep dog baby sitters.Requires???
Incomplete list but hopefully food for thought.There are ways to make money find Yours.
