virtual/administrative assistant (If only you are based in Australia)

Hi.
I have just begun a very small business. it is a one-man company at the moment. However, I do not wish to represent it as such. I need some assistance with following up inquiries, etc. For example, last Friday, I sent an agreement & an estimate of fees to two prospective clients, but haven't heard from them yet. So I will need someone who can call them and see where there are at and if they need any help. Later, I may need some email and phone correspondence with other clients as the business pick up.
My preference is that you are a native English speaker. I also hope that you have good interpersonal and customer support skills.

Thanks
