Corporate photographs

I am looking for a photographer to take some professional headshots of staff in my company. There are currently 23 staff members and we are looking to get photographs done of everyone. Our office is based in North West London just round the corner from Finchley Road tub station.
I am hoping that all photos can be taken in one day. This would mean only a couple of shots per person (maybe 3 or 4) to then choose from.

Is this something you would be interested in? If so, what is your current availability?

Kind regards,
Mary
