Have they assured you that they will pay up to $90k per year? If not, what happens if you get some admissions but they are all too expensive?
As a backup, check into ADN / RN programs at local community colleges. Note that these are often competitive to get into, unlike other programs at community colleges. After completing and passing the NCLEX, you can work as a nurse or go on to an RN → BSN program to become eligible for a wider range of nursing jobs (these are often less competitive to get into than other BSN programs).
