The company you speak of is called Enterprise cleaning of Ferndown near Bournemouth, they have at least 20 vans now ,and a call centre with girls phoning with the 8.99 offer .
I wanted to know more so I applied to work there, Ian the GM told me that "your sales skills and personality persuades the customer that they need stain removal, deodorizing,protection and other services" You get a van, prochem machine and no training for 140 /week .. you give the company 40% of your takings .
