No, that's not what she wanted to say. Starting a business takes a lot of overhead. A small firm with, say, 10 attorneys needs office space for those 10 attorneys, plus 3 secretaries, maybe a couple paralegals, add into that office furniture, computers, software, supplies, a law library (either an online service, or a more traditional set), stationary, advertising, any taxes or fees that may accompany starting a business, salaries and benefits for employees...the list goes on and on, and it adds up quickly.
Even if you cut the number of attorneys down to 2 or 3, it can still be a substantial cost.
