Electrical Questions

[Jason McK]

So in my new house I am taxing the electrical to the limit. It appears the circuit that the 2 tanks is on also is the same circuit a lot of other things are on. If I plug the Vacuum or dehumifier in it pops the breaker.
So I thought I'd get 2 15amp GFIC receptacles installed.
The breaker box is just on the opposite side of the wall to were I want the receptacles installed.
Can some one give me a rough estimate as to what this should cost. My estimate was well beyond what I thought it would be (but honestly I have no Idea)
