Yes, the above poster is correct, the support staff at Web Hosting Hub will have to install it for you, I had a similar thing come up with my website. Current prices are a $25 one time fee for installation and then for the dedicated IP it is $35.40 per year. Send an email to firstname.lastname@example.org and they will assist you with the installation.
As long as they can provide the information needed you can probably use the SSL, however Web Hosting Hub will have to install it for you. I think they charge $25 and then an additional amount for a dedicated IP.
