If you're good at something, never do it for free.
One of these days I was in the bank queue waiting to make a payment and I could hear a lady talking on her cell phone about a computer repair she had to pay. She was outraged because the value she paid was too expensive for "little" service.
"The support technician looked at the computer for only a few seconds, saw that the problem was a loose screw and after squeezing it and making a brief reconfiguration on the system, he charged me an absurd amount." - complained the lady.
So, here's my question: If the work was so simple why did not she go there herself and did it?
If the professional doesn't value his / her own work (excluding those who want to take advantage of it, obviously), it's very likely that practically nobody does. So, do it yourself.
