Hi Keith, congratulations!! :)

I'd recommend to get in touch with Ed Ferguson this is his web site:
http://www.cascadiadesignstudio.com/

His specialty is wedding rings and he uses MoI a lot as well, maybe he can set up something for you where you send some geometry to him and he could incorporate it into a ring without you needing to learn all the details about what's going to work and what's going to be problematic.
