House is 2200 square feet and needs inside painted. Not sure how much area there is to paint, not sure how to measure or estimate cost? I need a local painter to give me a free estimate?
If you are going to have someone else do it besides yourself then you do need someone to come to your home to do an estimate. In fact, I would get at least three different ones just to be sure.
Is it inside of your house that you are interested in? I would just call a professional painter. The estimates are free, and you are not under any obligation. But be sure to get different estimates as SuzyD said.
