I have a rough idea of how to install a lintel on an existing wall

such tools and thinking of adopting another method:
As others have said, you usually hire these.
How thick is the wall: if half brick (100mm), then I would want to
prop anything bigger than a single door opening. If it's a solid one
brick wall (215mm) then one option is to use twin beams: cut away on
one side, insert one beam, pin up and allow packing to set, then do
the other side.
