No best answer has yet been selected by moran. Once a best answer has been selected, it will be shown here.
For more on marking an answer as the "Best Answer", please visit our FAQ.Your question lacks so much information that any reasonable "guesstimate" is impossible. What size of house, what is your location, how many floors, what type of construction? More questions than answers I'm afraid.
Without more information even a guess would be impossible. If you post more information I'm sure that you'll get a decent response but in the meantime why not look up the adverts in your local paper and get a few quotes?
