Rhetorical question: Where did you source your original “individual industrial designers” from?
I ask from the position of jobsearch using key words “Industrial+Design” and “Product+Design”. Everything from sales reps. to engineers to graphic designers to CNC machinists (latest highlight is sales staff for the Apple Store that is about to open here).
Here anyone can call themselves an “Industrial Designer” regardless of training, skills or experience. The DIA recognises/ promotes url=http://www.design.org.au/index.cfm?id=187]“Accredited Designer”[/url] as having:
1.At least 6 years of combined design education and professional experience.
2.A minimum of 3 years of professional experience relevant to their design discipline.
3.An agreement to comply with a code of professional conduct.
4.A commitment to maintain their knowledge base through connection with the information resources of the DIA.
5.A demonstrated commitment to their design profession through membership and involvement with their professional body
Depending on where the OP is, perhaps their national ID body could assist?
