Advertising for bitcoin?
Ramps?

Yep.
If i can get from fiat to coins and back, im in business.

I think it can be done. Not very easy though. I think the hard part is going from fiat to coins. I think I found one site that would let me do it but it's only $25 at a time starting out.
Do you have a paypal account?

Coinbase was doing it for dollars, but i dont bank, so,...
Changelly was, too.

You might be able to put money on a prepaid debit card and then put that into crypto.

Or use local bitcoin.

That's an option especially if you are a seller. I think the buyers pay a pretty hefty premium though.
