My words of advice - stick to what you do well and let someone else do the things that you don't have the proper experience with.
"needs to turn her LLC into a S-Corp."
"Needs" to, meaning, someone is already giving her advice, and that isn't you? That election has been a common mistake seen here.
I recommend a CPA, not a lawyer, because the lawyer will do what you ask. The CPA should give you guidance, first.
"Level Up" is a gaming function, not a real life function.
If, after obtaining appropriate tax and/or legal advice, the client does wish to elect S Corporation status for her LLC, anyone can fill out the form.
As hinted at by the others, I can't think of any situation where an LLC needs to be an S Corp. I have seen many situations where an S election was made and should not have been.
