On the subject of websites, my favorite is Johns of Majestic. Its strikes home for its simplicity, its easy to manouvre around, & you can pursue the information you require quickly. I get fed up with these "flash" introductions, waiting for the web page to load. If you go to the really big companies, rarely do you get all these marketing presentations, just straight in, with the logo, phone numbers & menu.
I think you also have to think of your market & who is likely to use your services. Most of your prosperous clients who can afford to use a window cleaner, have seen all these fancy presentations before, whereas your average grandma/grandad who isn't up to the task of window cleaning anymore, will probably just about know how to fill his email in, let alone surf the web.
I also like P Fogwills updated site, with the use of gifs kept to a minimum, & with the find quick menu.
Just my views............ :
