I think Oregon Cryonics is starting as a community group and planning to eventually branch into the cryostasis side of things. But at present it is an educational organization, that works together with CI. The founder Jorden Sparks is a CI director.
So maybe that is the optimal path. Start out as a training and local support group that works with an existing org, yet have the goal of forming your own facilities if and when you get big enough. Perhaps I eventually could get something going in Idaho that way.
I also think expanding social services among cryos is an excellent idea. It doesn't all need to be done by the same organization that does the preservations. Charitable work done in communities by cryo motivated groups would be a good way to increase acceptance and build membership.
