get a professional cleaner to come in who will 1) move furniture, and more importantly 2) will put it back on either tabs or blocks. ive cleaned loads of fully furnished houses, and yes ive moved the lot and put it back.
shop around and instead of asking the usually boring ignorant question of how much? ask the proper questions, like....do you move furniture? what sort of machine do you use? how long will it take to dry? (can you garauntee that drying time?) are you insured? can you give me an honest opinion of what results your likely to achieve? do you rinse thoroughly? the list goes on but believe me, theres a lot to choose from when choosing a carpet cleaner. and theres a massive difference in service and results.
pay cheap and you'll pay for it.
