It is a very awkward-seeming phrase which it seems to me you made up, PBF. We cannot so often premodify so creatively, and though you can perhaps turn 'resource' into a verb without risk, I don't think that 'limitedly' will be a recognized adverb any time soon.
The expected is 'He's a student with limited resources who....'. If you want slang, you can say that he is 'a student strapped for cash'.
