Wow what a tough guy!
Speaking as one of the apparent punks how about giving a little more information about what youre trying to accomplish here?
Where are you located?
How is the building constructed?
How many apartments?
And while youre at it take a basic english/spelling class!
My typing/spelling sucks ,but you make me sound like a harvard grad!

In many cities you must be a licensed electrician to work on a multifamily building or a commercial building.

Also a separate permit may be needed to upgrade the service and the main panels. If not already, it is better to have separate meters (and main panels) for each apartment plus one more meter (and panel) for common area power.

In some situations (possibly required in some cities) the main disconnect switches or breakers must be located near the meters in a multifamily building. Here the "main" panels in the respective apartments are technically subpanels. This might make it easier for the electrician since the new meters and disconnect switches can be put in one place all at once, the new service lines installed, and then the power turned back on. From there the old wiring can be fed temporarily while new (sub) panels and new wiring are done slightly more leisurely.
