Well you dont have much time to get something together , you can only put in what you can do , how long have you been a window cleaner, Do you use a pole , if so how about a picture of you in action , also a couple of other pics of you cleaning other buildings . A couple of your customers coments saying how good you are , regular , reliable , also what other services you perform . Do you have staff , do they wear uniforms, Are you insured , are you in the Fed , anything to sell yourself . About the broucher as my wife says size does not matter
