Anyone self employed?

I make and install signs..my son and I have been doing this for 14 years now and business is booming despite the competition that thinks working for 1/2 of nothing is the way to go..luckily we are established with an excellent rep. But like rbdart mentioned the game with the IRS, insurance, workers comp, vehicle insurance..(I own a crane truck and a bucket truck)...I'd fire myself too but I don't qualify for unemployment..LOL...
