No, I'm making 100K at my day job. It's more convenient for health insurance and tax purposes as well. I can just adjust my withholding on the fly at my day job to account for my freelance taxes without having to do the whole quarterly estimated payments nonsense.
Another good portion of my clients are companies that need in-house apps or other programmers than need components or whatever. I really prefer those guys the best, they pay on time and know what they're doing.
I have to wade though a lot of fluff like "I want a game/app just XXX (Angry Birds usually :)" but at the moment even culling out all that I have more work than I know what to do with. I've stopped doing game projects, they usually turn into too much of a time sink and aren't worth it for what the client is willing to pay me. I usually do flat fee contracts, but work out the budget based on 75$/hr. Usually I do a gross "this will take 20/40/60/80 hours" type estimates.
