Your site has no mobile version. It's not fluid either. When I reduce the size of the browser your site looks all botched up. The Need Help? link leads to an email. You need to create a QA page explaining some of the questions/issues instead. Other than that the design (outwardly) is nice and clean.
Hi, Letsencrypt is the best SSL provider now, just need a linux machine. Try that. Only limitation is that it will have to be renewed every 90 Days. hxxps://letsencrypt.org/
Yeah, they are awesome! If you have enough access to your server you can just set up a cron so it renews automatically and you will never have to look at it again.
