Yes, you can pay managed hosting providers different amounts of money for different levels of support. Managed support will usually only monitor and fix basic infrastructure and respond to support requests from you. They often won't monitor or fix your applications/services; for that you can set up your own application monitoring and tests. NewRelic is a good all-in-one choice, but there are plenty more out there. To call you during an incident, you'd also adopt PagerDuty. In order to avoid service outage in general, you want to hook up some kind of monitor to something that re-starts your services and infrastructure. This will only fix crashes; it won't fix issues like disks filling up, network outages, application bugs, too many hits to your service, etc. You should be able to find small businesses who specialize in selling support contracts for all levels of support. By signing a contract and on-boarding a 24/7 support technician, you can get them to do basically whatever you need to be fixed when it goes down. I don't have suggestions for these, maybe someone else does (it used to be common for SMBs in the 2000's).
