What a lucky guy!
He's right, that will level the house. However, lifting and shimming as needed will also do the trick. I thought you we're maybe going to put a basement under it or someting like that. You stay inside with a 6' level and he under the house with 6-ton bottle jacks lifting a little at a time, till you tell him it's level. Then he packs shims or some other material at the top of that pier. Then do the next pier as needed, and the next, till everything is level.
Then it's time to repair all the plaster that has cracked from all the movement.
