NO way on the prices, every house is different, and you do not want to put your hourly rate on there lol
Just some tips, just take em in, I'm not having a go, or trying to be harsh.

I wouldn't put it on to be honest with you. If I were a customer I'd like to see a nice simple clean van, just with 2 or 3 signs on it. and
I would decide on whether you'd be reliable or not. If I would be a customer I'd not care about having that on your van. Wouldn't mean anything to me.
Just the name of the company, (I would go for something sounding more professional then 'reliable window cleaning'.....that just is a bit meh, I dunno. Don't want to come over too harsh)
Maybe AES Window Cleaning hehe, (Andy east Sussex window cleaning)) Under that : 'Domestic and commercial window cleaning' Get a professional logo made, so it looks the business.
Telephone number, mobile and land line, + email
Another sign ; your area that you work in. That's it, nothing more. It would be too much. I've seen vans, also on here I'm afraid which are just
way too much, if I see them, I just laugh. Looks amateuristic in my opinion, bit too pushy.
