I hired an electrician to put in a new/bigger panel with new breakers and it cost me $500. The panel is also where the elec enters the house from outside, so that would have to be moved also. You won't know for sure until you get some estimates. I got 3 estimates. One was $1800, one was $1500, and one was $500. The more expensive ones were going to do stuff that wasn't necessary.
