Why not install it yourself? By myself it takes under 1.5 hrs to do either end in the driveway by torchlight (shift work, so did it when I got home at midnight). If you don't have tools then now is a good time to get some.
Still looking for the right tyres for mine. Found a few other options of late.

Talking to a bloke as well a few days ago with Achilles Muddies. He was saying on road they were very quiet for the type of tyre they are. A little slippery in the wet tho but not too bad.
