There is always someone willing to shoot for less than you - fortunately some clients know the difference in quality and those are the ones I want to build long term relationships with.
I also get offers of having my name credited on the website/ magazine etc instead of $$$s, because it will get my name out there and I'll get more business. It doesn't work!
Next time I need a plumber to fix my washing machine I'll offer to put his name on my website as a recommendation of his excellent skills instead of a payment as he'll get more business from people visiting my website
somehow I don't think that will work so why should I shoot for free?
Exception will be for a trade for some pet project or something extraordinary missing from my port.http://www.whattheduck.net/bestof
