I'm actually handling most of the industrial design. The current format of the illustrations is accurate down to the 0.25mm level (everything pretty much works out to multiple of). If I was proficient in some 3D modeling package I'd go the whole way myself. Unfortunately it's not something I have the time to learn at the moment, plus it may be more information than I will need going forward since I don't know when I'll ever have the time to devote to doing this end to end.

What I really don't have experience with is DFM, Design for Manufacturability, though I'm not completely clueless about it. So I do try to take certain aspects into account in the initial designs, such as features that might make an injection mold impossible, etc. But again, I don't need this at this stage yet.

I'll send you some comps later this afternoon. Thanks!
