I’m not sure what versions of Sharepoint they support but keep in mind the older versions are getting EOL’d. Also, I’m not sure if they will host it for you or if they will work with Office 365’s Sharepoint Online, but if you haven’t managed a Sharepoint farm or don’t have a Sharepoint admin on staff I would stay away from it like the plague. That might be a slightly biased opinion based on flashbacks of trying to manage them though.
