build up in plenum chamber and tops of valves and ports as well as PCV and throttle body (s)

So that's 26 jobs down to 8 (unless you've never had a mechanic touch your car over the past 6-12mths in it's 10yr life which is highly doubtful) of which half are just 'checks' and the other half are straight forward work or 'if required' jobs.
Maybe you should take a closer look (or ring around and find out exactly what they do) then work out what you can do yourself and whatelse actually 'needs' to be done. Then re-ring places and get a quote on just those jobs and I believe the price would atleast halve (or atleast your local john smith mechanic could do).
