Most state engineering boards know that most IEs don't work for PEs. In general, the boards want to see some number of PEs (usually 5 or more) as references along with a reference from the people you have worked for. The PE references can be in other areas of the company, vendors, customers, former profs, etc. By the way, I'm putting on PE exam review courses for IE in Denver and Atlanta this fall.
