if it's your house and you plan on living in it, you can do the work yourself. some cities may make you take a short written exam, but once you pass you're good to go. if you don't know anything about electrical wiring, i would suggest that you go to home depot or lowes and pick up a book on residential wiring...this will help you with quite a bit.
assuming that you know how to wire the house and the panel, the next step will be to run a conduit and wire out to a meter base, which you will provide, and you'll connect to the load side of the meter base with your wires. if you'll have an overhead service drop, you'll run a rigid conduit and wire with a weather-head above the roof line, and the power company will connect to your wire at that point...if it's an underground service, you will need to run a conduit from your meterbase to their transformer or pole (in most cases...some co/ops will do this for you) and the utility company will pull their own wire in your conduit and make the connections at the meter base and transformer.
the first thing that you should do is check with the utility company to get a copy of their guidlelines for service installation. they will have a conduit size requirement, etc. also, they'll be able to tell you what they provide and what you're supposed to provide.
