You will need to email us to request a private SSL certificate. We use Geotrust's RapidSSL and Comodo's Instant SSL products which are cost effective and secures your site just as well as the more expensive certificates. We charge $75 per year which includes the install fee. If you purchase an SSL certificate elsewhere, there is a $25 annual installation fee.
For the Comodo InstantSSL the cost is $90/year.
