i'm fresh out of flight school (not some diploma program, i paid my dues and worked ramp through the whole thing

just joshing the diploma grads) now I've been looking for jobs for a month or two now and have recieved 1 phone interview and thats it. I have the option of keeping with applying to every ad on this site (and a couple of others) or my instructor has guaranteed me a position at the school if i get my instructor rating (schools expanding new fleet, international students etc.) problem is i'm reluctant to spend another 7-8K. should i take the offer or keep looking
I have:
210 TT
MIFR
