Cat Driver. We seem to be slightly at cross purposes. You seem to be providing advice for someone operating in the US/Canada FAA world and I to someone operating in the EU/JAA world.
There is nothing like the crop spraying industry in the EU as in North America. In many major countries it has been illegal for many many years... Spain being one of the exceptions means the schools are there. But even if you paid the large sums required for the rating you would be unable to find work as you are not Spanish and lets face it - a local boy is going to get the job over some pale faced limey who doesn't speak Spanish.
I am not "trying to sell that (JAA) BS to the rest of the world". I am merely accepting the fact that those are the rules that apply in this case. There is very little point encouraging a somewhat poorly informed your pilot with a JAA CPL to consider ag flying work in Canada/USA as on day one his lack of FAA license will bring avery premature end to his career there.
The best advice would be to try to find Glider Tug work but thats very hard IF you have no prior glider experience which all clubs like you to have very much indeed. After that its a Safety Pilot with a piston charter outfit but no pay and nothing for the logbook. Then it might be a FI course but thats five grand and there are a lot of unemployed instructors out there who cannot find work and have more experience than you.
Hobsons choice really.
Personally. If I had no lucrative desk job to go back to e.g. IT contracting, I would try to get a ground job in aviation. Ops departments, ground handling or maybe cabin crew. It will help keep you in touch with the industry and will only help when you do get that airline interview. Having Ops or ground handling experience might open the door into a part ground - part co-pilot job with a smaller air taxi outfit...
Keep your chin up.
