One thing that's been on my mind for a while is something I like to call AO Jobs. Start a new page on this site where prospective employers can recruit people from AO members. You could charge the employers if they find an employee or the member if he finds a job. The advantage of having this on AO as compared to another site is that the prospective employer could actually look at that person's previous posts and get a good idea of what the member is capable of. That would probably encourage better posting and it'll be great for the community as a whole.
