Need to level the foundation of my house

[Brandon Turner]

Hey folks, 

I'm looking to do an addition on my primary residence (live-in flip) and before I do, I need to level the house some. It's a post-and-beam house, with a concrete block perimeter. One corner of the house drops about 2 inches. I guess I'm wondering:

1.) Does anyone in Olympia, Tacoma, or Seattle have any good recommendations? 

2.) Anyone know how much this might cost? (I know... it depends. But ballpark?) 

Thanks!
