Roving Caricature Artists for Wedding Entertainment?

I recently attended a company function at a pub and they had roving caricature artists to entertain the guests. I'd thought it made an interesting entertainment item for bored people (oh we do have lots of those people at the usual weddings).


Chancing the opportunity that we might hire someone like them for our wedding dinner for entertainment, I promptly asked for their names and contact - Wilson Lee (drawing as below) and William Lee (cutter as on left). Don't ask me whether they are brothers or not though. I've their contacts with me but am not publishing them here for their privacy.

Might drop them a call if we are interested at a later stage.
