Hello, or should I say "G'day" :)
I'm very interested in your project. I love brainstorming (sad, I know, but true!) and would love to work with you on your fresh, new name. And I have to say- it's nice to see someone in your field who's bold enough to move away from the usual "Huffington and Associates" or the like. Yea, emphasis on the 'Ass' :)
Without knowing more about you and your business, here's what springs to mind initially;
Dollarize
(If based in WA-) WoggieWonga
Ca-ching!
Wallet-watchers
Money Men
Safe and Sound
Not a Load of Bankers
Three-Sums
Coinage
Of course, I could carry on, and I'm sure the quality would improve! As I say though, that's completely 'off the bat', totally uninhibited and without speaking to you about specifics or doing any research into, say, Aussie slang terms or current trends.
Thanks in advance for your consideration and, regardless of the outcome of my bid, good luck with this project and your new business!
Best Regards,
Mike Simpson
