Regarding German Work Permit while on Schengen Visa

[get2abhijit]

Hello,

I am an Indian resident, and have a Schengen Visa valid for 3 months. I need to apply for a long term work visa for Germany.
I am already in Germany on Schengen Visa. I have following questions:

1. Can I apply for Work permit from within Germany?
2. Since the answer for q1 is mostly NO, can I go back to India, apply for work visa, and then travel back to Germany while my Schengen visa is still valid, to continue my ongoing business meetings? Since it takes 6-8 weeks for work permit to be granted, I will be able to minimize the time lost waiting for the same.
3. Can I authorize someone to apply for the work permit on my behalf in India, and after it is done processing, on granting of the work permit, I can visit the consulate in India for stamping?

Any help or guidance will be greatly appreciated.

Thanks...
