Hi Aero, as you may have concluded your choices like those of many are severely limited right now but there are options nonetheless and it is going to take you some time to get up to speed so time is good!
I suggest applying in the USA for a cfi job, that market seems to be pretty strong still.
You can make a living and build experience once again maybe do the MEi and build multi time as you progress. Then hopefully in a year or two you can move into a regional.
Also the areas of China and India etc.. need to train many pilots in the future,
may be you could cfi for some such companies and make valuable contacts along the way.
Don t lose heart, you need time to brush up, and it will take time before either you or the industry recovers, so start out at the bottom and follow whats going on out there (pprune will be a valuable source).
The good news is your capital outlay should be minimal just get that teaching job !
Don t worry about derogatory replies here as some do not understand that not everyone is as up to date with current affairs as they are.
And good luck !!!. The road to success is littered with the talented, but those who persevere will get there in the end.
