Builder recommendations

I'd value any help you could give me about finding a reliable builder to do a kitchen extension in the Ruislip area. Ideally I'd like someone who can project manage the whole job including building regs drawings, finding a structural engineer etc. Have you worked with someone who was trustworthy, reasonably priced, had good ideas if there was a problem and saw the job through to the end? It sounds like a big ask now I've typed it
