Promote your website for low price is not easy. If you promote your website making payments of U$200 per month or more you are wasting money. The better way to promote your cleaning business online is place a link to your website from a well known cleaning related websites (that is for low price and sometimes free). In that way you'll appear in the first page of the better search engines without spend hundreds of dollars (some time thousands).
