In all my time doing birth related stuff, I've found that one of the biggest challenges has been finding the space to do things. Most of the time we don't need space every day, or even every week, and finding someplace that is cost effective, comfortable, and available is sometimes beyond our ability.
My dream is to have a birth professional's co op, where people can use the space as needed, for teaching classes, or holding workshops, or meetings, or consults with clients. Someplace that parents can call and get hooked up with many different services, and birth pros can call for space, knowing it's going to be a calm, soothing birth-friendly space.
Someday, when I win the lottery ;) Or at least find enough like minded people to start a LLC.
