I think it's best to just do the right thing for the games I'm making. I already contract out some of the artwork and sound design. My games don't make enough money (yet) to pay someone a full-time salary, but if the project warrants it and I can reasonably forecast how much money the game is likely to make, I would definitely consider that option. So it's not like I would just decide to open a studio some day. It's more like there has to be a game that's getting enough traction to justify increased labor expense or some kind of outside funding situation where investors are asking me to give them a big return.
