Photographer needed to cover an event on Friday

I need a photographer to cover a Charity Auction on Friday 29th April at 12.30 pm for a couple of hours max. The auction is taking place at Sandown Race Course, Portsmouth Rd, Esher KT10 9AJ. I need someone to take some pictures of a car with the person who wins the car with the charity etc. Full brief of shots provided. I need shots emailed to me straight after the event and these are press shots so I need full clearance. I don't need any touching up as we don't have time.
