I do a lot of this for ONE shelter. I cannot take on anymore as I am about to be really busy. I would suggest practicing on friends dogs first because, they do really need the help but, you better be able to direct them and do the job quickly.

I do about 80 animals in three hours, then run home, process them and get them to the shelter within about 12 hours. It is *alot* of work. I also run over and do their celebrity photos with animals. That isn't near the amount of work, but, you better know how to deal with people, posing and lighting(even if just natural light)

If you go to http://knoxpets.org you will see a lot of my work there. They haven't gotten up the new ones I did yesterday. That will probably be tomorrow.

My blog(if you go through it...) has lots of shelter stuff on it too http://JuliePoole.com
