Tami,

You might want to check out what the lady does at our shelter. She is retired and does this full time as a volunteer, she spends hours touching up the photos. She does a really wonderful job:

She has someone helping when she does them. She kind of glosses over the cats but does a great job on the dogs.

Also, all the photos at my link are of shelter rabbits. They let me bring them home and shoot them overnight, 3-5 at a time, and then I would drive them to get spayed or neutered the next day.

Then there is the company I used to work for, which you could apply for a job at, photographing pets at Petco all year long. They have a contract with them. You will get oodles of on the job experience. If you want to PM me, I'll give you that info.
