Pay them and they will. The problem with many people bemoaning the lack of Fortran and COBOL developers is that they are not willing to admit that the code they "need" to maintain isn't actually valuable enough to be worth paying what that maintenance costs.

It's like complaining that no mechanics work on carburetors anymore. Well some do, but they are expensive and not worth it to keep your old hoopty running. Might be worth it if you have a show-quality 1960's era muscle car.
