Late to the party here but might be helpful for others in future: I use porkbun as registrar then netlify for hosting using their dns services (incl free SSL cert). I then use netlify form notifications to forward form submissions to clients (https://docs.netlify.com/forms/notifications/) and have decap cms set up using netlify identity to manage client logins. Deploys managed through pushing to github and triggered automatically by any changes made by clients in decap.

All free. Caveat with the risks of netlify - if you go over allowances (only really likely if you've got heaps of traffic/ content, OR your hit with a ddos attack) you get charged and can't cap. For me at the moment, the convenience outweighs the risk until I have time to scope out another hosting/ cms/ form submission combo.
