As for the invisible fence company charging $105 for 15 minutes, that does not justify the amount. I charge what is both fair and so I can make a fair profit. Now if it takes more than 15 minutes to locate (max) then I would charge more. Piece work must factor time as well so you have a proper pricing structure.
You, of course, are free to charge what you want. Yes, the ideal method is to precall (more time, manpower, etc...) but when you get your orders in the AM and you are a one-man operation, then it becomes unrealistic. Now, as I stated earlier, if your contract does not provide for dealing with these u/g opsticals, you need to renegotiate the contract immediately.
