Liberty for quickest option- definitely not the cheapest though.
They will give you something close to 50 credits for your pilot certs and your type rating is a class too I think.
They have 8 week semesters and you can take four classes every 8 weeks. So in a regular 16 week semester you could earn 24 credits. That is a heavy load and I would not recommend it, but its what I am doing with the aviation classes.
If you have no college it would be financially prudent and fast to do all of the general education at your local community college online and after getting AA or AS degree transfer into Liberty or another school to complete their bachelor's program.
You could do dual enrollment at a community college and at Liberty at the same time to do it even faster if you could keep up with the coursework
