Thanks to our Supporters
When you are approaching a project and a lifestyle change like this, help comes from some pretty unlikely sources. Ryan Tollefson has been a good friend in answering questions when I call.
He sells Unity Home Group, but also has a focus in Scottsdale, AZ and has plans for a location in Maui.
Thanks guys. I could NOT attempt something like this without your friendship and help.
