A 70th Birthday present

I would like to have a cartoon drawn as a 70th Birthday present. The family are putting together a book of stories as a gift and I would like a cartoon of myself and the person whose birthday it is of us drinking a bottle of very good whisky whilst playing snooker in a very small table ( which we did together on a family holiday many years ago). Can you recommend someone who would be able to do this quickly ( in London best as I live in London) Problem is I need it before 31st December!!!
