I suggest your first port of call be the local PEA office with the address and the meter reference of one of the existing meters (so they can accurately pinpoint where you are). EDIT A Google maps printout wouldn't go amiss too.
They will tell you where they can install a meter, how big a supply you can have (important) and be able to point you at a "contractor" who can give you an estimate.
I put "contractor" because most of the PEA offices have crews who will moonlight for jobs like this. Our poles were put in (on a Sunday) by a crew driving a PEA truck and wearing PEA uniforms, the poles are stamped "PEA". Pay the foreman in cash!
I think we paid about 15k for 4 poles and 60m of single-phase wiring, but that was waaaaay back in 2011.
