$2,700 to paint 2K sf house reasonable?

[Jack B.]

Interior paint only. Includes paint, which he estimates to be 8-10 gallons, going from yellow paint to white, will need two coats for sure. It's the old paint from when I bought the place 6 years ago. 

I thought about doing this myself, but it would take me a couple weeks with a friend. This guy can finish in 2-3 days so I can actually get a tenant back in there, the last tenants were rough on the walls. I kept 1.5K of the deposit for this work. The $2,700 is the contractors cash price, and it seems like it's worth it to me, especially including materials. Frees me up to find other investments rather than paint...

Should I hire him? I do want to be clear on the cost and type of paint, double coat, where is being painted, with the contractor in writing though yeah?
