Re-reading my previous post, I realize one could misinterpret the intended message. Not at all suggesting that one does not try continuously to improve one's craft. I am constantly trying new technique, angles, etc. in spite of the fact that it is not reflected in increased sales volume. Just trying to inject a dose of the practicallities faced in this particular market.
Mike, in your area there is a well established photographer who covers the agility circuit which could present a significant barrier to entry in that space. Just coincidental that I'm aware of that because I only know of one or two in the US and one of them happens to work in PA.
