SSL and HTTP to HTTPS

I need to turn on the SSL and redirect HTTP to HTTPS to avoid a NOT SECURE warning on my websites. I tried with http://dougshear.com. When I click on Activate SSL it gives me the following message: Domain cant be verified as it doesn't exist on builder. I have looked at some community messages regarding this, and it is above my pay grade. So how can I find someone, I will pay them, to remove this problem. The websites have been with Homestead for decades. Fastest way to contact me is dougshear8000@gmail.com.
