I am running a photo competition at work as a team-building experience (insert gagging here). Although I trust my co-workers to submit some beautiful images, I'm a little worried about the evaluation skills of the managers I've chosen to act as judges.

I will be meeting with the managers/judges in Perth, Australia at the beginning of October. Can anyone recommend a professional/semi-professional photographer in Perth whom I could contact about giving a half-hour lesson in how to judge photography? (images are mostly going to be landscape, with a few people and macros thrown in).

Thanks a bunch,
kim
