Nice thread Julian,

I currently use both hourly rates and quotes, depending on the client. A lot of time, programming work will be hourly, as anything can happen, but when I'm working with design, a lot of times it will be quoted. Programming rates can go anywhere from $35-$100/hour, while I've had ecommerce sites go for as much as $3k-$5k. It all depends on the client, as you said, and the complexity of the site. But it is important not to undersell yourself, and your time. The client is paying good money for a professional service, and If you can prove to them your services are worth their time and money, it should definetly be worth yours.
