I applaud your efforts to reach out and expand. I split my time between Florida and Michigan. In my rural area of Florida I have a choice of 3 guilds and several less formal sewing groups. In Michigan I live in a large metropolitan area that only has one huge guild which meets on Tuesday night when I have another commitment. I would love to be part of a guild there but there are none that I've found that meet at a time I can go.
As a guild you might also look to your members as a source of referrals. Have them invite a friend etc. or send out invitations to referrals.
