have a look in your local area as many areas will have a photography club and they will meet on weekends etc. They tend to pic a different location each outing (normally weekly) and often they help each with settings and how to take a better photo and frame it better etc.

I think learning this way is much better and more practical than a tafe course (did that years ago)

not sure where you live and what style you want to do, though I will recommend building your skills before offering weddings, and with weddings a great idea to team up with someone to cover different angles and just in case you miss that critical shot otherwise the married couple could be really pissed if you don't deliver. As for portraits etc photographers charge a ridiculous amount for packages, undercut them by 25% and still make a nice living.

good luck with it.
