The other option I heard about to add HTTPS to a website was to use Cloudflare. Cloudflare makes this an option even on the their free account. Since I was already using Cloudflare for one of my websites, it turned out it was already turned on and I could test immediately. There was a great article on how to configure it at https://raventools.com/blog/free-ssl-http2/.
The next step will be to do the migration steps.
