Great work Alan,
I have to say the same as Sean, (You need a studio) I know you said when you retire.
So retire and do what you want to do and You know photos of dog shows and the dogs fetch some really good bucks. think about what you really love to do and the contacts you have in this business. Your a good photographerand you know your way around the business. do your self a favor and go for it. (the proof is in the pictures you take)
Just some words of encouragement my friend.
Good Shooting.
Cheers: David
