Mmm, I think I like the top one best, and I think you are right to splash the fact that you are a 'different' type of window cleaner.
Most people don't know the first thing about Water Fed Pole window cleaning, or 'Ladderless window cleaning'
But it does differentiate you from others.
Slightly smaller on your name, and slighter larger on the fact you are a window cleaner.
I'm not sure I agree with the statement that a mobile only number makes you look like a gypsy/traveller either.
How many of us don't use a mobile now?
I hardly bother with my landline, all my customers, or potential customers get given my mobile, it's how people get hold of me!! Why waste time routing a call through your landline??
To much info though just confuses, some vans go around with so much 'stuff' written on their vans, you can't work out who the hell they are, or what they do!!
By the time you have worked it out it's too late.
