It is good to start a sitting group. My suggestions are:
Make the group as informal & self-reliant as possible. 'Self-reliant' means making it clear that meditation is an activity of self-practise & self-endeavour; that the group provides individual members the support & opportunity to develop their own practise.
Make it clear/overt it is simply an informal sitting group rather than a formal teaching facility.
Provide guided meditation only to newcomers or when introducing a new practise.
Keep guided meditation short (e.g. 10 - 15 minutes) & main meditation long (e.g. 30 minutes).
If there is no guided meditation, do a text reading at the start, contributed & read by yourself or by a member of the group.
If possible, end with tea & formal group discussion on a topic, chosen by yourself or by another member of the group.
