At a good regional:
Year 1 - $21k-$28k
Year 2 - $32k-$45k

Figures include range of lowest possible (rate x guarantee) to a high range that assumes average 95 hour line and per diem compensation. In other words, it's what you are guaranteed to make to what you could make if you like (and are able to hold a high paying line) to work more.

If you don't want to include per diem, minus about $5,500 from the top end pay rate. Of course, you will eat free for 2/3 of the month (because you are getting paid to eat), so factor that into your monthly bills.
