You should put this in items wanted.

Not sure if this helps, but i made one last week to post a bass within the UK.

Get two strong cardboard bike boxes from Halfords, and an hour or so with a Stanley knife and some gaffer tape.

Cut one of the boxes into an oversized guitar case, and cut the other box into sheets/smaller pieces to reinforce the back, front, ends and create a cradle for the neck/headstock. Pack the rest with crunched up newspaper or bubblewrap, and you'll have a free, very light, very strong container for shipping.

Gear4Music was fine for me when I did this. The buyer paid for a case to be delivered to me and then I used the box to send it to him with the bass inside. Worked out really well actually, with the seller happy with everything!
