C.P.
LinkedIn (www.linkedin.com) is a great professional networking site. It's free (there's a premiere version which costs but that's not necessary). His profile should resemble his resume - he can search others with similar backgrounds for ideas. He should start connecting with former colleagues and friends plus join some appropriate LinkedIn groups (again - check groups like professionals have joined) and actively network within those groups. They also have job postings in the JOB section as well as in the groups. Recruiters actively network on this site, as do hiring managers.
