Midgets For Hire

I`m looking into the possibility of hiring six midgets for an elaborate practical joke for a best mans speech at a friends wedding in London June 2010...

I appreciate they may well come in the traditional 7 dwarf package but I only need half a dozen... Don`t mind paying for the extra one but he`ll need to wait in the Van..

If you could point me in the right direction I would appreciate it.
