Boat party

I need someone who has experenices in organising a Boat party before which will be held on Thames river in begining of Sep. You need to take us (20 people) from Leicester square to our boat(there will be another 150 ppl go to the boat directly themselves) which you have already booked at 8:30pm. And organise an one hour performances(maybe a singing,dancing live show). The boat party should be end around 12:00 mid night.
You can join us for the boat party or you can leave us when the boat depart. However, you need to be reachable on the phone at any time that day.
