price varies area to area..
But the thing to do is bring on board a professional or two
I have a nurse,( ex matron and nursing home manager --30 plus years)that weighs up all sales for sick room treatments also to supervise as required, otherwise no insurance and legal implications with local authority- she earns more than me off each clean
For pet cleans ,parvo outbreaks etc-- a vetinary research fellow
Stables --- the OH is BHS trainer.
Its the only way to get the work experts with letters after the name lawyas impress in this area
For party cleanup -- i utilise the services of the oldest swinger in town /
