Very nice, works well. However I would put a very clear, bold sentence on there that states this is just an estimate for guidance and all pricing will have to be confirmed upon arrival. I've lost count of the number of lounges I've turned up to clean that were only 3m x 3m according to Mrs Customer over the phone, and they suddenly doubled in size between the phone call and the appointment!
Be prepared for 6 pages of the same old whinging when people pick your prices to pieces! As long as you're happy charging what you're charging don't listen to anyone else
There's 2 schools of though about publishing prices on your website. On one hand some folks say never do it because it allows your competition to undercut you, and also some customers can get put the wrong information in and get the wrong price which will cause problems both ways round (under or over quoted)
The other way of looking at it is that giving people a rough idea of what you charge will stop the price-shoppers from pestering you, if they have a "half price in your area for 2 weeks" leaflet in their hand and are phoning round trying to beat the prices on it!
