We recommend A2 Hosting, we use them for the main Realmac Software website. A2 obviously works great with RapidWeaver’s built-in publishing!
Check them out here: https://www.realmacsoftware.com/rapidweaver/hosting/
FYI: We get a small kick-back from each sale, so when you sign-up via our link you’re also supporting us 
Cheers
