PLEASE HELP – moving a sidebar

Hi Guys,

I am trying to move my left sidebar to the right (so I would have 2 sidbars next to each other)…I am a bit familiar with html…but not great…
As you can see at http://www.foodforkids.net.au I have moved most of it..
But I think my CSS needs editing – not sure where to go from here..

Can someone take a look and offer any advice – the black box just needs moving.

Thanks
