Hi Shane,
All my work is compact and done fortnightly and is done using the traditional method . I would say it would take about 2 days per month - I can do it traditionally in a day and they are done fortnightly - WFP 1st clean will certainly take longer as I know this due to selling rounds and also my window cleaner who cleans my house is WFP and I clean more than him per hour traditional. Also there is lots of scope to get more work...
Thanks
