What is a good price for legal (re)structuring?

[Aaron Rosenberg]

Of course we all understand that legal protection is a must.  It is worth every penny to hire the appropriate professionals to make sure your business is lawsuit-proof and pays as little in taxes as the law allows.  Well...not EVERY penny.

I'm shopping around to have this work done and I'd like to know what it should cost. Even having a simple LLC made can cost anywhere from $150 to well over $1000 but the work is the same. So I'm looking to find out what the community thinks is a proper price range for a project of this magnitude, or at least what is TOO much to spend. e.g., not NOT use LegalZoom. They are an overpriced brand name; nearly anyone else will make you an LLC for less.

Suppose there is only one owner for everything.  That means there is a trust or C-corp that Owner has 100% control of, and the trust owns five different LLCs.  Looking for ballpark estimates on what this project should cost. 

What can one expect to pay for this?
Anyone known to charge too much?
Anyone known to be an industry leader that serves the BP community?
