How much for dog boarding kennels when you need to go away?

[Piffle]

Have 2 JRT pups 3 mths old, both innoculated wormed and stuff, will need to get them looked after for a few days and was wondering about cost and whether they can board this young?
Or should I ask a neighbour to help for money (next door has son aged 20 who works nights he likes animals)
They have the run of the garden all day and the garage for shelter.
If he could just tuck them in at night and let them out in the morning, they are crated and if taken out by 8am don't usually soil...

seven pounds per night per dog for a cheap place (doggy equivalent of a cheapo B&B, does the job, feeds, walks, somewhere to sleep, but not exactly welcoming or attractive!)
ten to fifteen for "normal" place
anything up to gawdknowswhat for a posh, luxury pooch hotel where they aren't put in a cage, ever and are able to sleep on the sofa and eat steak!

thx have found a few locally and will be prepared not to freak out
