I used to work at FSI in SAV. Salary was $70k to start and they provided the type rating (G-V). Great people, great sims, world class facility to teach in.
Cons: Schedule is constantly changing. You are expected to carry a crew through the whole program, 2 FTDs and 7 sims, so you will work 9 on with 0 to 5 off each crew. If you teach the GS portions you will work M to F in class and fill in for sims on the weekend. Forget flying for a client as you won't have the time, so no chance to make extra $$ or stay current.
All in all a great place if all you want to do is sim instruct or if you lost your medical. OTOH, you will be making half what your students make and will have to say "zero hours in last 12 months" on any applications you fill out.
Think long and hard, I loved the place but am lucky to have escaped to a flying job.
