Teachers -song and dance

Hi, everyone. I just had my WAAPA audition, and they said to go to jazz class and get singing lessons for a year and try again (nicely, of course). I'd like to know if anyone knows any good teachers or places go go for singing/jazz lessons. Starving uni student here, so anything comparitively pricey will be out of my range. Also, any tips on how many times a week I should go to lessons, what to look for in a teacher, or anything like that, would be really welcome. I'm not a complete beginner, but have been busy with Yr 12 for the last year, if that helps.
