Small portrait drawings at the event -- 2

Hi! I am looking for artists to generate small portrait drawings at an upcoming event. The desired size of the portrait drawings is 15 x 25cm or even smaller. The style I have in mind is one that I will provide the details for, so I'm looking for someone with experience in creating quick (5-10 min) portraits sketches. I would like a total of more than 10 portraits completed in the timeframe of the event. If you think you have the skillset and availability to make this happen, please contact me with your portfolio and rates.
