It seems like you built a product that you want. You've made the assumption that people other than you don't like using freelancer.com or CL. To me it doesn't make sense to try to make a product like this without first having several people tell you why they agree with you (that the status quo isn't good enough) and what they want different and are ready to use your beta when it is ready. Then use it yourself to handle your overflow. If that works well for people looking it may generate organic growth. But as others have said, use reddit etc. to keep getting more people to try your product and give you feedback.
