A certificate will be generated automatically and a redirect will be in effect once you set up the DNS to point to the OwnerRez hosted website as outlined at the bottom of this article: https://www.ownerrez.com/support/articles/hosted-websites -- that may take an hour or two after the settings are in place to generate, but will happen automatically.
I had a look at your DNS settings and they're not going to OwnerRez at all currently, but to CloudFlare. Since you're using them as an intermediary, you'd need to set up the redirect on that end. Or change the DNS to point directly to OwnerRez.
