Your biggest competition is probably livecareer.com they have an outdated Flash/Flex product and poor user experience. They have the SEO for "resume builder" locked down through use of fighter sites and multiple domains.
In addition to layout templates that you guys provide, they also provide quality content templates. Most people suck at writing the resume content and that is a core need.
In addition to the content need people don't see the value in using a pay for resume service when they could just do it them selves. If you can provide some metrics that like 75% of your users got a job afterwards then you have some more value.
