If this was a negotiation involving PUPR or even the more intelligent ones amongst the inner city warlords, we would be in real big problems and I would probably be dead within just days.

The bolded phrase doesn't sound right. There are two ways to fix it:

1. we would be in real big trouble
2. we would have real big problems

You could also go with "really" in place of "real" -- that's just a matter of style preference since both are grammatically correct in this case.
