Talk with Jabil. Their suite of services can help you with all aspects of the design, build and fulfillment aspects. You bring the idea, funds and go to market strategies.
Haha definitely do not do this, unless you have a million dollars to burn.
Seconded. I also strongly believe that if your hardware product is your core competency, it is designed by your team primarily, of course a consultant here or there can always do a good job spicing things up. I personally feel like turnkey product designs services are best suited for companies that have a specific accessory or something that needs to be designed, not the core product.
Thirded. But they probably won't talk to you anyway.
