Welcome to ZooChat. What about the websites of any agricultural type colleges in your area (I say "type" as they all seem to offer much more these days)? A couple of colleges in my area offer suitable courses and most of the keepers at my local zoo have been students at the closer one. The other has close links with Flamingo Land, so wherever you live I'd have thought there could be something similar - that is presuming you do not live in East or North Yorkshire in the first place.
