Conservatory cleaning - Techniques & pricing help please

[Iron Giant]

Just out of interest what would you price this conservatory at ?

Very little fall on that roof cleaning but more so rinsing if its minging won't be easy if you only have a backpack, Access to customers outside tap would be a must.

If buying a backpack go to gardinerpolesystems.co.uk far better quality going off what other lads have said in the past I have a Gardiners backpack and I am very pleased with the build quality.
