Wanting to start a northern LA support group-advice/suggestions

I live in northern Louisiana and much to my dismay there are no support groups for adoptees in my area. I am currently in the brainstorming stage of figuring out how to start a local support group. Does anyone have any advice? Do you think it would be best to be led by a mental health professional or would it suffice to be led by a member of the adotion triad? I've got so many ideas floating around in my head but I'd love if anybody has any recommendations about starting the group. How to find meeting places, publicize the group, how to conduct a group, etc. Thank you in advance for any advice you can offer. Peace & love
