Some ideas:
Telecom services include construction drawings etc... check out General Dynamics, Bechtel in their telecom division (website).
Alternative Energy is getting bigger.
Download the bailout bill and scan through it. There are a lot of goodies for companies.
e.g. Wind farms need construction drawings etc....
Register yourself as a company, setup part of your apt/home as an office and expense the square footage to the business (takes off something off your rent/mortgage).
Do some research into alternative energy, that field is really going to kick off.
Look at things like natural gas pipeline layouts, windmill structures, energy efficient modification of existing buildings including schools etc......
Think out of the box.
if it means doing a short course on environment etc... do that.
Go to your municipality and find out how you could provide your expertise to their zoning board for any construction project from telecom towers to renovations & new construction.
Just a couple of ideas off the top of my head.
Good luck Bro, you'll make it..........just think outside the box to use your transferable skills across industries.
