This is question has a fine line.
What is full time? When your sole income is when your a LCO? Or when you put more than 32 hrs a week in?
What is part time? When you have another job? When you have two incomes? Less than 32 hrs a week?
I have two businesses that are seasonal. The first in landscape/hardscape and everything else in between. The other is from Nov - March which is taxidermy. I mount deer and other critters during the winter. Oh and I do a lot of hunting locally and out West. For ice management and plowing I bring back my guys for storms and such. I have to say I feel blessed that even in this bad economy I have thrived and grown. I just moved into a 1500 square ft warehouse with an office to use as my new shop and storage.
