Keep at it man. I knew a few guys with 6-700 hrs private multi on their dime, ended up with Atlas as flight mech's within a year or two F/E then straight to rt seat with ATP minimums. Another observation was WOA, hired plenty like yourself, put them in a sim and 50% F/O lower 50% flew sideways. Guess what I am getting to is mabe a F/E job may pay the bills and get you a shoe in the door if the opportunity presents its self. I know the market was different a decade ago but as for all of us saccrifice usually pay's off.
Best wishes.
