I have been cleaning carpets & upholstery for a while now and have ventured into contract cleaning which I hope to develop but I have been asked to quote for a Builders Clean (pre-handover) for 90 houses. They are 4 b/room with 1 ensuite. What is the best way to go about pricing this and are there any pitfalls I should be aware of? Thanks in advance,
Regards,
