Might I suggest something in aircraft leasing? Or engine leasing. Can be extremely lucrative and the experience of being a pilot is an obvious advantage.
Another suggestion is teaching aviation English to non native speakers. Can involve travel but there are places where the students go to the college. Not sure if it's that lucrative.
I am always banging on to young potential pilots that they should go to college first. This is an example of why it's a good idea. Even if you succeed in getting the job there may come a time when it loses it's appeal. If you have an MBA or something similar combined with your pilot experience you can often be appealing to a wider cross range of businesses.
The reason I emphasise that is because my main experience is as a pilot, unless you count factory work and an obsolete job I had when I was working my way up. I couldn't even get a barman job now.
