I used etyres the mobile firm link
http://www.etyres.co.uk/ this last year for two cars. They fitted pilot sport2's and Contisports.
The fitter was ace did them on my driveway, I watched like a hawk, but he was a good lad anyway. That's the point they come to and it's more personal. So tell them your anxious about damage etc and you'll be OK.
Also competitive prices and I haggled a bit too.
