Would it be easier to bill the guild as a PI firm? We could give ourselves a fancy name made up of one or two of the character's last names or we could name it after a founding member who is no longer alive (or active in working). Just some ideas along the same vein.
As for me and time, Sunday evenings are open for me again, although I am in the east so late for me isn't necessarily late you for. Cy is central, isn't he? This is a busy time of year for me, so I would not be able to be on a whole lot initially.
