What general aviation operators might hire a low time pilot?
Getting your instructor certificate is your best bet.

Beyond that, there are jobs out there for traffic watch, banner towing, and flying jump planes for skydivers.  Also glider towing and sightseeing.  Ferry flying is possible, although I'd be careful of any place that would hire you with very few hours -- they may be cutting corners &amp; guys with more time look at the operation &amp; say "no thanks."  Not necessarily, but be cautious with anything that looks "too good to be true."  

All of these are typically positions that only have a few, or one, or no openings at a time, and those spots are in pretty high demand.  So persistence and personal contact (not just sending a resume) are probably vital to landing one of these jobs.  The place where you're most likely to have more options is flight instructing; obviously that requires the CFI certificate (or equivalent for outside the US).

Good luck!
