How to set up a Pimms tent?

We are running a Pimms tent at our local garden party. It will be a big event and we want to do it properly. I've seen on the Pimms website you can buy jugs etc but does anyone know where we can get big Pimms umbrellas etc and can we make big signs for the tent without infringing copyright laws etc? Has anyone done a Pimms tent before? If so please share details! Thank you in advance x
