hello need some advice on this matter / when i approach a potential customer offering my window cleaning service asking them if they have a window cleaner ( if they have i do not pursue it any further.) but if they say that they have but are not happy with him/them does this cause a problem i am only asking this because i will be a one man band when i start. i could ask how much does he charge and the customer could say less than what they are really paying thus making it seem like am undercutting if i accepted - i would never undercut but i want to gain new buisness in keeping with the proper protocol and not seen to be poaching someone elses work. i knqw the customer has the right to decide who cleans their property and i am only trying to earn a living, l have not started yet because i am canvassing areas but would like some good advice and teqniques to handle such matters and any other to help me on my way to being professional and successful
