Hi DG.
If not said already (not read all posts :
)
Push out the frequency so it allows you to charge £10 minimum.
hope this is say 8 weekly and not 12
you will need more work obviously, go out canvassing as if your starting again from scratch, are you wfp?
tell custy your different as yoy clean frames panes and sills and windows stay cleaner for longer hence 8 week clean.
when you have alot of work convert existing custy's to 8 weeks.

Not easy i know but the best things aren't
good luck
