ATP is an expensive and a min standard pilot mill. The main attraction during low time hiring frenzy's was the higher amount of multi time you get and promise of an in-house CFI job. In this day and age, you'd be better off to save your cash and stick with a small time local school. Good chance you'd find a CFI who wasn't a PPL six months ago...

Anyhow, the main thing is to get up through your CFI and get a job. If you can build your time up to 135 mins (1200 hours), it's not too hard to get a night freight job with very little multi time.

Is there any way you could go part time with your current job and work on your flying part time?
