I always charged a fair price for good work. If you work too cheap your reputation suffers.

The one question I always asked the "whiners" was, how come there's never enough time or money to do it right, but always enough to do it over?

Many times the customers I lost to a lower price were back six months later to have the low cost alternative made right.

Stick to your guns, if your work is good you'll come out ahead in the long run.
