I would recommend emailing them or go out there on the weekend and drop your resume off. With 300tt it's very unlikely you'll get the job there. Most skydiving companies want 500tt to fly a 182.

There are actually quite a few skydiving companies in the Indiana, Ohio and Kentucky region. You'll have to do your homework and search. Pull out a VFR sectional and look for parachutes. Figure out what the name of the skydiving company is and send them an email or call them.
