I work with wordpress a lot (not as a developer but user) so I am throwing in my 2 cents. Wordpress is a very competitive domain where you are competing with many developers from all over the world (think elance, odesk etc). So you have to price yourself based on value and not just a number. For example, if you say that you charge $50/hour, you can never compete with an ok developer from India/Eastern Europe charging 10-15/hour. So forget the hourly stuff. Talk about the value of what you have done with wordpress. Do you write about it ? What problems did you solve and for what kind of clients ? My advice: talk about the businesses and their problems you have solved using wordpress. You can always talk about how you used wordpress (customized a theme etc) but for what purpose is the key for clients. Once you can talk like this, you can also charge based on value which means charge a fixed fee or daily rate etc. For example, lets say a client wants to build a custom plugin that you know you can do in 5 hours, why tell him/her that ? Figure out what value it adds to the client. Then price your work accordingly. Sure this does not always work the same way for all kinds of jobs but it can matter. Editing a theme's css is probably very simple for most wordpress devs but creating a custom plugin for a specific purpose may not be.
