300 odd from Nationals and some our own but most are subbed out as not enough hours in a day as most need doing early doors. As poor as made out to be i actualy dont think they are bad earners. We goto most high streets local where we do a lot of retail outlets and spend a 3-5 mins at each place with some being 10 mins being bigger stores.
As an example in Bromley we hit Vodafone, Pizza express, Ask, GBK, Zizzi, Your move, 99p store, both Waitrose stores, Bathstore, Subway. All get done in just under 2 hours as regular weekly and some 2 weekly jobs. None are great earners but all together earn a realy noce start of the days take. Yes some are priced poor at £6 but some are £10/£12 and £20 which none need deep cleaning as so frequent as they are happy with what gets done and sign the work off. To do 1 or 2 in a high street isnt worth it but doing Multiple you can do quite well from it and it all gets paid in the bank end of each month without any chasing.
A normal house front and back £15 takes 15/20 mins which is good. 12 shop fronts in a high street averaging at £9 each taking 5 mins a pop...Work it out yourself.
