Invite women to come out to visit and bring their dog(s) and male friends along as well.
Have options for a shorter visit: an overview and walk through of the buildings/property then a short walk in the woods or meadow. If puppy dog likes the place it will make a great impression.
For longer visits: Host educators from the nearby town to present sessions: gardening, how to do it 'off grid', our water source etc.
Maintain a list of reputable references from the nearby town that can vouch for what nice respectable fellas you all are.
Perhaps rent garden plots to allow woman to first create a relationship with the land. This may also be an opportunity to welcome older women to the property to provide a sense of security to the younger ones.
Talk with the Ministers, Chaplains etc of local churches about your education sessions and garden plots as well as your sincere wishes to offer a home and lifestyle for some suitable young women.
Good luck!
