Focus group moderator required for October

My company is conducting some market research to identify which client demographic will be most receptive to our business. We run entrepreneur accelerator workshops in London and keep the numbers for this small for a better quality of program. My business partner and I would like to run two focus groups in late October. This will be after hours on a weeknight and the venue will be in London Bridge. We need someone who has experienced in selecting candidates, mediating the focus group as well as collecting and analysing the results.
