Bill, I know little of corporation law (other than what I heard/read in one class in 1978, and passing a bar exam).
But this is a subject easily researched (from a comfortable chair).
https://corporatedirect.com/start-a-business/entity-types/s-corporation/https://www.google.com/search?q=pros+and+cons+of+s+corp&ie=utf-8&oe=utf-8&client=firefox-b-1All I can point to is:
1) does her consulting work present any significant risk of liability? is there a need for corporate insulation from personal liability (vs, or including, liability business insurance)?
2) if she incorporates, she must scrupulously follow all the requirements of meetings, minutes, records, votes, or whatever they are (even as a one woman show), or risk having no insulation from personal liability at all.
3) incorporation is often for tax benefits (especially S corps for a small or one man show), but it's my (limited) understanding that there has to be X amount of money involved before there actually is much tax advantage (over a sole proprietorship), or it may even be higher taxes. I do not know what that money amount is today, but it used to be more money than most individuals made in a year. And both state and federal taxes are at issue.
If she has some kind of business plan, she could talk to a business planner or corporations lawyer and ask if an S Corp is a good idea for her. For a consult fee. A good lawyer should tell her if it's a bad idea for her, rather than convince her it is and sell her a set up package anyway.
You never go to a lawyer (or consultant) to hire him, you go to interview him for your job, assess his competence and work ethic, get him to tell you what he can do for you and what it will cost. If he passes the interview, you might hire him. Or try again.
If you can afford F Lee Bailey, you can skip the interview and just hire him.
