I'm with the guys who say to go to cargo. Summertime is a great time to get comfortable with single pilot operations, then survive a winter in hard IFR and you'll be "line current" and very confident for your next step.

If you don't have the 1200 hours for part 135 IFR PIC, you might try "VFR only" operations in places like LAS and PHX where they only require the PIC to have 500 hours if they're flying cargo or less than 10 PAX.
