Landscaping

I have a 4 valve sprinkler system that is about 10 years old. Every week or 2 I have to replace a leaking diaphragm, o ring, etc. I'm tired of it and want it cut out to the manifold, they part that is leaking currently, and replaced with new manifold and valves. I have some general trimming that needs done I can add on to make the job a little bigger. Will pay cash.
