90% of my work are hotels that are all 4/5 floors high, for this i use a 40ft carbon pole. whilst it is "harder" than cleaning houses, as they are smaller, it isnt that bad.
The poles i make are made of carbon fibre. due to the way the material is produced, the poles are lightweight and strong and also they are "slimline". the biggest diameter of a 7 section 56ft carbon pole is only 44.6mm wide.
whatever pole you buy, i would recommend getting the best you can afford. ive seen alot of people try to save a few pound by buying cheap poles, which sadly dont last long, and are not "user friendly" :

.
Also IMO you are more likely to make better money on higher buildings, as they are prepared to pay more for having the cleaning carried out, plus you find you are saving alot of time compared to someone who would be cleaning off ladders or cherry pickers etc.
Hope all goes well for you!
