Contractor recommendation in Newton, MA?

[drawz]

I just bought a house with an 18x18 garage made out of rusty tin. I'd like to tear it down and start over to get something a bit bigger. Looking to get 20x20 at least, but bigger if possible. Goal is to comfortably park two cars and hopefully have room for a small amount of storage.

Does anyone have any recommendations for a contractor in the Newton, MA area?

I'm open to any other advice too!
