To my knowledge, there are no current permit holders or commercial outfitters/guides who are approved to guide/instruct rock climbing in the Poudre zone of the Canyon Lakes District. You could try Kent Mountain Adventure Center or Colorado Mountain School if you'd like to climb in the Big Thompson Canyon or Estes Park area. IMO those companies have better terrain in the Estes/Big T areas that is more appropriate for groups.
You could contact the Roosevelt Canyon Lakes Ranger and apply for a temporary permit for your group. If you need a Fort Collins based AMGA person, PM me.
