My in-laws found some guy pretty cheap but he was exterior mostly.
If you want it done right I suggest you rent a good commercial sprayer, buy two 5 gallon buckets of paint and do it yourself.
It'a a hassle I know. But I did it with my house and did a better job that I now I would have gotten from the "low bid." Now I did have to spend a good deal on the best masking tape (blue) and bought cheap plastic jump suit, two pair of goggles, and two light weight hoods to cover my hair.
I woudl however if doing it again rent heavy tarps to cover the floor. As the lightweight one's stuck to my feet once they got wet with paint.
Take the money you saved and buy a Fridge to put into the garage or a new wasehr or dryer.
