HI there,
My name is Andrew and I'm from Australia. I have vast experience in excel, however have only just joined Freelancer (yesterday!), so have not developed a rating as yet. Your project sounds interesting, if you are willing to give someone who's new at this a go, hopefully the price should be very competitive!
The time difference is around 12 hours between Australia and USA - I'm not sure if this will be an issue for you but will need to be considered as it may stretch out communication.
I look forward to hearing from you.
Kind Regards,
Andrew
