Plumber required to change self cutting tap to T connection for outdoor tap

[PHinett]

Hi,

I moved into my house which had a pre-existing outdoor tap, but the water flow is terrible and i'm led to believe this is down to a self cutting tap only cutting a tiny hole.

I am looking for a plumber to change this to a T connection, outdoor tap is directly behind the sink on the outdoor wall and is currently connected with a small piece of hose pipe.
