I'm working on the content for a course that I hope to attract freelancers to - about client management and engagement. However, I'm not sure where to advertise once I'm ready to roll it out. Does anyone have any ideas - I'm going to target independent industry bodies in various industries as an obvious first choice. (although part of my preparation is working out what industries have the kind of freelancers I'm talking to). And similarly, I'm looking at industry newspapers etc. But what about web forums? I've heard of some of these freelance job search sites? Any that I should particularly look at?
