Fly fishing desktop tools - industrial designer needed

Hi,

I'm looking for a freelance industrial product designer to support the development of a novel 'tool / gadget' that will be sold within the fly fishing market.
The new design is looking to expand an existing product range featuring the same core technology. I have an initial idea of what it could be but looking for this to be challenged and expanded upon.
This is a cost sensitive DFM project, with the upfront investment in tooling sensitive. So please reference the relevant experience you have in either design for injection moulding or similar process.

Help needed:
- idea expansion/ further concepts - 1.5 day: output = hand sketched and annotated thumbnails,+ 1hr call to discuss.
- Proof of concept CAD - 2.5 days: output = medium fidelity rendering to detail product function, .Step 3D data for RP.

Note: design is commercially sensitive so will need to be happy signing an NDA.
