Hi yadreamin,
I didn't intend to insinuate you were looking for a handout! :o Understand you may as well rent from someone here than a complete stranger.
That link might be helpful if you get no takers...
I know you're probably hoping to help out someone here by filling their "house" for a week, but have you checked http://www.stayz.com.au/accommodation/sa?
We've used them in the past for Vic, and been happy.
(PS. Only one E in Glenelg ;))
