is this a business opportunity?

A guy by the name of Ryan requested a very simple pacman game with his picture
and then some other random people's pictures on it that he would use
for some prank of some sort. The game can be accessed here.
I made this simple game in less than 2 hours, and I made it for free.
But then when I finished, I realized how great of a business
opportunity this could be. I could be daubed the pacman masta, and make
pacman games with people's faces in them. People could request their
pictures to be put in a pacman game, and I could sell it to them for a
very low price.

What are your thoughts on this? Is it a good business opportunity?

Uh, I guess so. Lol this is a pretty strange idea but I like it.

haha... that would give me a kick! good idea, if u had other games you could do this too as well. and if you came up other ideas for this u should make a site.
