Welcome Maya,
.18 cents is a very good starting point, the average is around .20 cents. We do .14 cents for the rough clean and .06 cents for a final. If we only do the final we charge .12 cents for the final. Remember this tip, "the better your rough, the easier and faster your final will be. Windows at $8.00 is also very good that is about the going rate. Remember them window sills thay are very nasty at rough, work all your windows; frames, sills and screen very good at the rough. In post construction your screens are normally new, so not much actual cleaning goes into screens, we do not charge for screens. For your final it should be very much be getting rid of final dust and flloors. As far as marketing the same techniques apply, go to construction sites and post flyers in the document boxes, try to meet the builder or sight foreman, go in the yellow book and mail flyers to your listed contrators, etc. The local chamber oo commerce or builders association list ways to contact building contractors. After your complete cleaning always leave a flyer behind, the future owner may want to use your services for future seasonal cleanings. Enjoy it......
