Locums to help pay off student loans?

[FridayImInLove]

Hey there, ICU nurse here highly considering applying for CRNA school as soon as I nail down this GRE. I was wondering if, upon graduation, working Locum gigs in addition to a perm staff position can help expedite paying off student loans. How much can one stand to make on a locum type basis? Is it advisable to do both at the same time? Is it even possible? Any input is welcome. I appreciate your time.
