you could become a patrol pilot.
when i thought i didn't want to be a cfi, i made a few contacts with some people doing traffic and pipelines and stuff like that. they usually don't care if you are an instructor. one place wanted you to have 1500 hrs tt, but they were paying what i would call above average.
really, you should just bite the bullet and get your cfi. i eventually came to that decision and do not regret it. being a cfi is an awsome learning and networking tool, and the best part is you can usually do it on your schedule. this means you can keep your bread and butter "day" job. also, if you freelance, you can pick and choose who you fly with. being a cfi is much more fun when you choose your students v. having to fly with every warm body that can make it through the door of a flight school.
good freelance cfi's should be able to bill ~$50/hr, and even at that price, have all of the business they want.
as a side note: for any of you sweating getting the cfi, don't. i know that there is some stat that states like 7/10 cfi applicants fail on the first attempt, but i honestly don't see how. aside from covering different aspects (teaching) of things you all already know how to do, the cfi ride is NO harder than any other checkride. i took mine with my local FAA inspector (not a DE), and it was no big deal. the best part was, since he was an FAA employee, the ride was free.
make up your mind to do it.
study like you have a brain.
don't freak out on the checkride.
charge enough for your services.
help people become safe pilots.
be your own boss.
build flight time.
it's easy and fun.
good luck!
