I believe that experience and maturity should matter.
Young people can be very creative and innovative.
Older people in the industry can take this biz more seriously than younger ones.
You can tell how creative they are by their portfolio and you'll know how serious they are in their work if they're reliable and efficient in the delivery of their works.
But you can be ripped off by both young and old.
In the same manner, you can never tell by age if they are trustworthy or not.
