towing course in melbournes west or Geelong

Can anyone recommend a good towing course in the west of melbourne (or the other side if I really have to) or in Geelong (better than the other side of town)?

I know many say they aren't necessary and that practice etc etc.....but I need to learn to reverse my van properly as my partner doesn't drive. When I tow a trailer I just take it off, turn the car around and rehitch....I have practiced a bit and am slowly improving but think I need someone with me to help me through it. I will be spending good money on a car and van so think it's worthwhile to invest in a towing course. I plan to have my partner and our 4 kids in the car - so I need to be able to tow confidently and safely. So far the only one I can find is a tow-ed one but sadly it only has one date in december which will probably be a little too early for me (ie may not have car/van yet) and nothing for next year yet (I've emailed to ask)....are there any others?

I'm asking for recommendations of ones you've either done or know someone who has but also if there are any that are to be avoided good to know.
