Careers.SO has two faces—candidates and employers. It seems like you were trying to create a candidate profile, even though you were looking for someone to hire. For this reason, your profile is "incomplete"—it's Careers' job to find you a job. If you just want to use it as a CV but you're perfectly happy and aren't interested in getting a new job, that's fine—but your profile isn't complete because it hasn't met its purpose.
If you want to hire people, however, you need to either post a job or search candidates from the employer side. This works differently—you don't create a "personal profile", but this is the right way to look for people to hire. If you select "post a job", you will have places to fill in a form that's sort of a company/job profile.
