You might be old, but what qualifications/time/experience?
Some of us have come into aviation rather older than their early twenties, but that can be an advantage in Business/Corporate aviation if you have useful business/management experience that can help in all the other aspects of running an operation, rather than just flying an aeroplane as in the airlines.
However you're still going to need the flying experience to be of interest, and there needs to be an opening whereby a company is willing to pay for your type rating.
