Are there any companies that will let a 17 year old travel overseas and work with animals? ?

I am 17 and from Ontario Canada, i wish to be a zoologist when i grow up. I would like to travel to another country to work with animals for 2-4 weeks. All the companies i have found you must be 18 or older. I wish to do this in the summer of 2009.

Maybe try the Roo Gully Wildlife Sanctuary in Western Australia.
