This obviously doesn't hide the RepairShopr.com web address from the end user, but what about doing a 302 Redirect for the time being? i.e. setup repairshop.mycompany.com on your own host and have that host do a 302 redirect to mycompany.repairshopr.com. The links you send your clients could still have your branding on them, but their web browser would seamlessly redirect them to the secure page at the repairshopr.com domain. No SSL errors. True the client would see the RepairShopr.com domain name in the URL bar, but the truth is as long as they are not getting an SSL error I'm willing to be 50% or more of the people that use your link will ever notice the URL on the page they are looking at. If someone actually notices most won't care... and those that do and happen to ask just tell them yeah, that's the software you use and that yes that's legitimate. At least until custom SSLs are available :)
