What to pay a Game Developer?

I have found people that make games in Unity and have thought about going that route but because you avoid the 5% fee. I originally thought it would not be charged if I paid someone to make a game but found out through the answer hub that as long as the game engine is used you have to pay it.

I really like the engine, enough to use it and pay the 5% and it has so many cool things that make it worth while but I just need to find developers in Utah I guess.
