It's a pretty impacted field, but it does pay well.
In 1997 I started doing web programming and design. I started out by charging $55/hour. Today I charge $50 per hour for my low end clients and $90/hour for my high end clients.
It's fun once you get into it too. I love programming! Finding clients is challenging, and people are learning web design on their own a lot now.
However, the best part of all this is being able to program your own site. If I had to pay a programmer to handle the Vegfamily .com updates each month, I'd probably be out of business.
