I had a 2 year service done on my GT/s recently at JCT600 Leeds. I first called an indy and got a price of £450 + VAT and then called JCT to see what they'd do. It suddenly went from £1400 inc. VAT to £750 + VAT=£900.
I'd call the MD and ask them for their best price, say the car will be 5/6 years old when the service is due and your in two minds between MD and indy and I bet they give you a better price. Worth a go for the cost of a call.

I can argue to reduce the air filter cost as I have a BMC filter and I could easily supply oil at £50 from Opie.

As noted, 1k or under is your target, potentially supplying your own oil. I can't see the Strad being any different to a standard car - no reason it should be.
