You have several good answers in this thread already.
In some areas it might be legal with the proper permit for you to do the
work or part of it. In others areas it is not. Since you had to ask the
question, I would suggest that you at least get the service entrance and
breaker box installed by an electrical contractor.
The new entrance and box would be called a service upgrade only and would
not require that the whole house be brought up to code at one time. This is
the best way to start the project even if you plan to do it all later.
The actual wire pulls and circuit connections can be done by a competent,
educated DIY person. If you choose to go this route take the time learn
about wire ampacity sizes etc. It isn't rocket science but to be safe you
need to learn these things.
It is unlikely that you will be able to get a firm estimate of doing all the
individual runs. Those are usually time and materials. There are just to
many things that might add to the cost for anyone to give you an estimate
that is fair to both you and the contractor. You should be able to get a
firm price on the service upgrade. That is pretty straight-forward.
The price of the service upgrade is going to vary widely by location. For a
200 amp service in most parts of the US the prices already quoted in the
thread should be in the ballpark.
There is no way anyone here can tell you exact price w/o taking
a look at the house. I new someone in exact position.
Price he was quoted - $4000.
It took a day of work and $550 of supplies to replace 60A service
with 200A. Later he called electric company and mentioned that
service wire felt "warm", got free service upgrade....
Whatever you do, make sure you get a permit and have the final
product inspected. It usually is minimal extra expense, but if for
some reason you get an electrical fire, your homeowner's insurance
carrier eill have a hard time denying a claim...
A local man did some self wiring, and even thoyugh he followed code,
it was done without permits and inspection. He had an electrical
fire. It was determined that it wasn't his fault, nut insurance
denied his claim. While it was not a catastrophic fire, there ws
property loss and he had to handle it on his own.
