Ever consider advertising phone sex lines? that's how I got started - there's $0 overhead, just start posting the number on classified ad sites, and writing it in bathroom stalls haha. I signed up at alwaysphonesex dot com, they give you a free 888 number and some pictures and landing pages to promote it with.
If you're feeling generous, you can sign up under my aff link (
www.alwaysphonesex.com?offering=769) which I'd apprecaite obviously haha, if you don't want to sign up under me, don't. just type www dot alwaysphonesex dot com into your browser and don't click the link.
Hope this was helpful. I make a decent amount of money through my 888 number, and back when I was just getting started it was the only income I could maintain haha. Good luck.
