TV presenters

Hi all I noticed there wasnt any area on here for presenters but I thought I would sign up anyway due to the help i see people getting in other fields. I am wanting to persue a career in presenting a need an agent who is not a rip off and says that i have to do there expensive course before they sign me up. I ma looking at saftv in Sydney which is around $2000 for a part time 10 week course anyone have any ideas on courses and agents in sydney?
