Hi, I'm a fellow Australian and I've been freelancing for over 10 years as a Multimedia Designer, for agencies and studios in Melbourne (Clemenger BBDO, Ogilvy and Y&R to name but a few).
My rate is Au$35 p/h. I can deliver a really professional animated banner, which is consistent with the look of your site, for approx. 7 hours of work including reiterations.
Let me know if you are interested. My bid might be higher than others, but I'm sure that the added value I can bring to this project is worth the extra money.
Kind Regards,
E.G.
