As a first time seller, how do I get a rating? What are the other restrictions?

[yatto1951]

I reside in Australia and I have a very good rating as a buyer.

I have never sold any items on eBay and have 100's of items I wish to sell.

Is my rating as a buyer a good indicator for potential buyers?

What is the price limit for my first sale/s and am I restricted to selling only within Australia?

To answer your first question, no

Buyers can only be given positive feedback so even the worst buyers that ever were will have 100% 

But before anything else, have you fully completed sign up to Managed Payments, and been approved/given the go ahead by eBay to start selling

You will have to do that before anything else
