Boy, you can start for way less. Go with Buyshared.net reseller plan (2 USD p/m) which includes blesta. Your only other expense would be the domain name, which costs 12 bucks a year.
Usually, in the control panel of the VM provisioner, there is an easy backup solution that can automatically send back-ups to an SFTP server somewhere. That's the easiest way.
Depends on what your business is. If it's just a news outlet then a simple Let's Encrypt certificate will suffice.
If you have a lot of accounts and thousands of dollars in revenue then go with a certificate with an insurance policy.
