Theres no shortage of low time pilots, and almost nobody will hire you for a 135 PIC at 500. Your best bet is find some local 91 gigs, get your hours up and get on SIC with 135. But beware of the contracts, if you plan on going to the airlines you will be stuck at a 135 for longer than your ATP mins.
Or just CFI, won't have to relocate and fly your ass off.
