As far as a beach is concerned, to set up first I would imagine the sponsor would have to hire the space. then set up a stage, supply power. Lay sand, provide deck chairs etc, staff it every day, security and first aid etc all day 7 days per week and security during the closed hours. also advertising etc and paying bands and artists to appear on stage + disco for when bands arn't playing. There are probably a few things that I have missed out and these are my own observations, but I wouldn't like to pay for it. I know the cost of some of these things are crazy. SB
