Basically as stated above, you're going to need to get your CFI, or have some really generous friends to pay you to fly their planes. No one at a commercial operation is going to hire you. Now maybe 2yrs ago, they were pulling anyone with wet-ink on their Comm/Multi to fill the right seat of all the Regionals, but that's been a moot point for over a year.

To be competitive for that type of job you're going to need 500+(more like 1000+) TT with who knows what MEL time.

Being a CFI is going to enrich your knowledge of flight, and if you don't feel you've learned more as a CFI than you did as a student, you weren't trying very hard! Plus this gives you a rating that I highly recommend you renew every 2 years regardless if you use it or not!!!

Anyways, I digress, get the CFI, learn something, teach others, get paid to fly, build that time, make the connections, and get the job you are truly seeking. Good luck!
