Maybe you could offer your services over long distance (the client would have to pay transportation/housing)? Probably a dumb idea on my part, however from the work I have seen you do, plus your vast engineering experience, I would think that someone out there would be willing to pay for your skills level over some of the low end "handy men" that do not have even a quarter of your knowledge or skills.

Would keeping the surface of the pond moving help to keep it from icing over? Is the issue with the pond icing over actually about temperature or the fact that there is no gas exchange? Just curious, I've never had a pond. This can help with very mild freezes (using air stones or other aeration devices. The concern with the pond icing over is gas exchange, however in very shallow ponds freezing is also a concern. With proper planning in cold winter climates, this should not be an issue.

I have had my pond for Two years or better, I live in NC and I havent had to put heat in mine at all. Just having the water moving kept it from freezing over. granted I did have a little ice in spots, but it didn't freeze over the whole thing. My Koi are doing great. and getting really big. But I do have a water fall that does help keep the water moving, If you are putting them in a tub, you could go to Lowe's or some place like that and get a small filter and it will keep the water moving just fine. I have kinda built my own filter box, which has really kept my pond clean. and I don't have to clean the filter off No more then twice a month if that. winter I dont clean it at all. I had gotten a rubber made container, bigger then the filter of course, put holes in it about 2" wide, all over it. then got some of that blue or green filter mesh stuff you would get to put in a regular air conditioner, and packed it all around the filter.. You would not believe the dirt it collects! its awesome, again keeps the pond clean.

Gas exchange. If the pond ices over completely, the oxygen/CO2 exchange can't take place and the fish eventually suffocate.
As to your question, surface agitation will definitely keep the pond from icing over, provided you can keep the mechanism that is providing said agitation itself from freezing.
I run my waterfall all winter - the hose that runs outside of the water is insulated with 1" of foam and buried under about 300 pounds of rock. I also use a 1500W de-icing ring (similar to a cattle tank heater). I have never had the pond freeze completely over and we have days/nights where the temperature can get 20 below zero F.
