In addition to the reply below, I imagine there are some other less costly online services or cheeky ways to send money through PayPal, Amazon GiftCards, Western Union, Bitcoin, some other strange way that one can think of with credit cards or bank transfers.
If a service is really that useful, and the person behind it is already demonstrating to me that they're trustworthy, I will bend over backwards to jump through hoops to pay them.
Otherwise I wouldnt be buying in the first place :)
Not affiliated in any way, but Stripe offers a service called Atlas that will help you with the paperwork so you can begin processing payments. Setup fee is a one-time payment of $500 but be sure to read the fine print as there are other yearly costs you need to take care of.
-Try to emigrate to a country with a strong tech sector and get a day job there.
-Build a web service that people love and will pay money for, because it does something very useful for them.
Everything else probably isn't going to result in you making money.
