Different Aerial Imagery/Patrol jobs?

Hi guys,
I am in the IT field and am finding out that I hate it more and more everyday.
I do not want to be working in front of a computer for the rest of my life. I
started my business and I guess I am doing okay, but I'm 23 years old and want
to fly or do something with airplanes. I keep finding myself hanging out at the
local air museums/airports here in town and can't seem to pull myself away. I
occassionally do some aerial photography work in the area and love it, but
there's not enough of that kind of work down here in South Texas.

However, I am at a loss as to what specific aviation jobs are out there in the
world. I like the following: aerial photography, wildlife, patrol (non-law
enforcement), ranches, small towns, single engine aircraft, cropdusting (if the
pay is decent), aerial firefighting.

Can someone help me connect the dots and tell me what aviation jobs may
interest me? Is there a list somewhere online where I can get an idea of the
different types of jobs involving the use of an airplane?

One more thing, I have a bit of hearing loss and so I am sure I'll be limited
on some of these jobs.

Thanks for any advice!
