I've just started trying out these keyrings, these are the prototypes.
I will customise these for your fursona, it's $10 for the original art and $3 for each keyring. Once you've got the art you can get multiple keyrings and you can do different characters on each side.
Postage in Australia will be $5 per shipment (I may reduce this later) and I haven't figured out what the international postage should be, so for now it'll be $5 too.

In about 2 weeks I'll have decided if I'm going to FurJam, if so I'll take orders to be delivered at FurJam to avoid postage.
