Actor Wanted For An Event In Bromley Green, Kent - In August - Date To Be Confirmed

I have kind of a unique request . . . We are from Houston, Texas and visiting London for the next three weeks. My daughter has Down Syndrome and Autism. She is totally in love with Jim Dear (from Lady and the Tramp) and she is convinced he is her boyfriend :) Now that we are in London, she is repeatedly asking to see him. I am trying to find someone to hire to play the role of Jim Dear for an hour or so and have lunch with us (I am flexible as to location) at an Italian Restaurant of some sort that is similar to Tony's from the movie.
