"Undercutting" comes naturally early in your career. You do not have the experience quite yet to be charging what experienced ops charge. Make sure production knows why though, as you don't want them having high expectations. Also, don't take a gig if you aren't ready for it. Word travels fast which can either work against you or for you. Best of luck and you have us all for information and help.
Also, nothing against Greg but taking a SOA workshop will also work in your favor. Many experienced ops to learn from, giving you exposure to different techniques from different people. Discover what works or doesn't work for you. You will develop your own style in time, generally a combo of what you have learned from the various instructors.
Any questions, feel free to ask.
