Now, no matter where you live,your commercial success is determined by your competence more than any other factor. If your skill level is about the same as "Mr Fix-it," he's your competition. If, on the other hand, you can do something he cannot- who cares what he charges?
Now I am perfectly content to let someone else change lightbulbs and apinted-over switches. Sometimes they get ambitious and try their hand at other stuff....and make a mess of it...or run out of tricks...and I get called.
Now I look at this as an audition. Funny thing is, simple courtesy to the guilty party will often result in him initiating future work for you. He'll say,,,"Boss, we really ought to call John and ask him."
