Hello there,
Even though you mentioned you want someone from Australia, I am still writing this proposal to inform you that I am working with several Australian clients and can work with you to understand your requirements through Skype as well.
Also, I have done several Quotation builder tools that made the quote generation process very efficient for the clients.
If you could drop a message to me, I would be able to share some sample screenshots of quote generators of varying complexities. Also, if you could explain your requirements, I can assure you of a system that will work exactly as you may have visualized.
I am an expert in Excel as you would see in my work history here on freelancer and have completed more than 475 projects with consistently 'Excellent' ratings from clients across the globe.
Look forward to working with you and thank you for considering my bid.
Regards,
Rishi
