Tours, skydiving, pipeline, mapping, traffic watch. These jobs are out there, and not of much interest to 'shiny jet' pilots (pay might be one reason). You must have 500 hrs for 135 VFR ops. Become familiar with the 135 regs, mins, ops rules, duty/rest, etc. I left 121 to come back to 135 (flying a Beaver on floats, it's a gas), and I'm almost the youngest guy on the roster at 40. It's not a 'nowhere nothing' job, when you find a niche that few can find training to do. BTW, I'm still working with a decent wage while many of my 121 regional buds are working at Home Depot for food money.
Keep building your hours. My advice is to always go for the PIC time. Forget SIC until you have what you need in PIC. That means finding a company that'll start you off in a single, say a 206 or 207, and move you up to a twin after proving yourself. Build the twin PIC until you have at least 1,000 hrs, then you can go and sit right seat somewhere else.
That's just my take on things. Good luck!
