I hate to start with I think, but I think you've got 120 days to get your 100 hrs in the airplane (OE time can be included). If you still don't have it by that time you can fly a leg with a check airman to get 30 more days to hit 100 hrs assuming that you haven't already hit day 120. At the end of those 30 days (150 now) you're going back to the school house/box if you still don't have the time.

I was in this position not too long ago and second what the other person had to say. Call your CP and ask for some trips. It's what I had to do and I even got to cherry pick the trip I wanted. I was told the only stipulation is that the pilot you're taking the trip from has to agree to it. I don't think it's too hard to find folks willing to sit at home and get paid, though.
