Caricature sketch created for web

I need a? well drawn full length caricature sketch done. I will provide head and shoulders photo for you to work from. The body can then be added in by you? so the character is wearing a jacker, jeans and trainers. ( I can provide specific details to the selected person). Ideally I woudl like to see rough sketch (maybe of just head and shoulders) of what it will look like to check before final piece is completed so I know it will be the right style. The? caricature needs to be a little humrous and fun in style. The final piece is for the web so if you draw using graphics tablet might be better. But if you like to draw in ink etc then that would be fine - but need final sketch as hi resolution jpeg I am on a tight deadline - so I ideally need this done in the next week
