Have you looked at colleges/universities that have co-op education (alternating study for one term, work at a company in relevant field for another term)?

For typical STEM-related work term jobs, the money (after expenses during the work term) is enough to cover most of the costs for the next study term.

If co-op education is not available, then you'd still have earnings from three summer jobs to help offset the cost of going back to school.
