Collect a toy music instrument from Greenacre, NSW package and send to South Australia

I have an item that I've purchased on eBay that was "pick up only". I'd like to pay someone to collect it for me, package it up (will need a large box and bubble wrap) then post it or courier it to me in South Australia. The item is a plastic toy musical keyboard (large but not heavy) so I'm proposing a fee of $70, which will cover the actual the freight costs, and the remainder as your fee. If you get a good price on shipping, this should leave $30-50 as your service fee. I will arrange the collection details with the successful bidder. The task should take less than an hour if you're in the area.
