Need Wedding Cake Stand in form of a Sleign...

Ok... so we're having a 'christmas theme' wedding and really want to put our wedding cake (which will be in the shape of a present - bow and all) on top of a wire sleigh as seen in the picture... minus the scary Santa Claus.
Any ideas as to where I could find one - we've only been able to find wooden ones - but who wants splinters in the wedding cake... plus the wire looks classier.
