I would first call around and see what the going rate for CV is in your area. Here in chicago, its not economically feesable for an AV company to do Central Vac. Last place I worked did it on a limited basis, but we could not compete with the companies that specialized in it that were paying their pipe guys $8.00-$10 an hour with no benefits.............

The concept of Central Vac is also very strange to me... For the price of a CV system you could put an Orek XL on every floor of your home (Amd most rooms in some cases) and then not have to lug around the goofy 30+ft hose kit....

Very Strange..........
