This is what I will do.
$1k, put it into one touch, cut a penny sleeve into half and place one half on top of card before placing one touch cover, stops the card from moving.
Assume this is domestic. If same state, meet up to do transaction.
Postage - discuss with seller.
If interstate and using Australia post, go for Platinum express post, insurance up to you. Platinum express post is pretty much express with signature and the last few express post from interstate has been one day delivery.
Courier - never used them so will see what other members say.
If overseas, use Fedex or DHL international for now.
Good luck.
