you can do lots
You can do alot in 9 weeks. You should be able to get both your instrument and multi commercial faa certificates. Be very careful where you go, and what schools promise though. Since the market is bad, and lots of schools are hurting for students you should be in a good situation. Make sure that whatever school you go to, you will be able to fly every day. Thats harder to do at big schools. I know my used to work for as a cfi for a small school and also at a big one. The larger schools were by far the more expensive and took longer. There are some great deals out there now. If you want some info on my old school send me an email. Best of luck on the new job, and on the flying you do.
