I'm an Aussie too!
We are both pro VO artists with pro studio gear.
You can check my samples in the portfolio, and here is a link to my colleague Graeme's voice (he will be the second person).
I recently completed a 70,000 word e-learning dialogue project, and am very familiar with what needs to be done.
My bid is $120 fixed price for the lot, and assumes they are all of similar length.
Cheers
