This isn't a job for an amateur.

And if you don't have a service valve in the street/pavement then you need to book an outage by asking your water supplier to turn off when you want it off and on again when you want it on again.

Unless you have a brilliant reason not to, now would be a good time for you to run a new MDPE main from the distribution pipe at your boundary to a new stop tap inside your property.
