So you will be a manger or an Educator?
My advice is to find out the salary range you will be on-
then you'll feel comfortable negotiating.
Ask for mid point of the range at least.
If you are going to be a manager, make sure they place you on the
manager scale.
Point out the benefits you bring to the job-
credibility w/MDs, how you will save them money through
increased nurse retention,how you plan to help
meet JCAHO standards, etc.
Sounds like they want you, so don't undervalue yourself.
Ask for other perks- education reimbursement, journals,
membership dues, etc
Good luck
