I am sorry, but i don't get such a web site. I don't even see the reason of such a website.
No selling point what so ever.
I know your excuse that you want to make it simple, but it has to do a purpose - sell your service.
Think at it as you are new potential customer would you call to owner of this service without any further search for a window cleaner ?
I am in the process of getting my website done, and I can't stress my self enough how important that someone looking at my website DO NOT LOOK ELSEWHERE AND CALL NOW.
as well as
if they are looking for window cleaner - THEY GET TEMPTED TO OTHER SERVICES fascias clean, cony clean, gutter clean etc.
I am sorry if my respond is a bit harsh, but I am just honest.
