Hi,
fixing a dripping tap is surprisingly simple. Getting the bits might be a bit trickier unless you find a local hardware store and can work your way around...
For repair stuff like this online I usually type 'diy' with my search terms.

just watch out...once you know how it's done...you'll be required to become a 'mr fix-it'...

might also need a wrench/spanner to do the task...
