I find it hard to believe OP has bought everything they would need, unless they only work on just 1 job and only play that one job and don't/won't level anything else. That's really only one of 2 possible reasons to not have anything to spend soldiery on. The second reason is that, you do have other jobs leveled and have made enough successful runs in second coil and have been lucky enough to get all the HA pieces and weapons for the jobs you play.

Otherwise.. there should still be things you could buy with soldiery.
