My friend posts videos on YouTube. After all is said and done, he makes about 1 dollar for every 1000 views. At that rate, the girl in the video above made almost 2k, just off that one video. Not bad.
Nope, what matters is if the wife likes it. :D
I do have a question about your requirements, though. Are you and your wife okay with no electric starter?
I buy flour tortillas from a place that makes them while you wait, but I make the corn ones myself. I bought a nice wooden press in Tijuana, and just buy the masa already prepared. It's about as easy as boiling pasta.
