Its all legwork, lots of time, lots of phone / email work, and finally, a bit of traveling.
Though were a design studio, we are also working on
Cord Order, a cord management device.
We have tooling done for the plastic mold, and are getting bids on the foam. Then, we'll find someone to put it all together.
Through networking, we found a high-quality (ISO 9000) China manufacturer who can make a larger tooling for ~10,000$, but we can then mass produce the product.
Just put in your time, get referrals (even from other companies who are related to your product, but can't manufacture it), and keep a log.
Its good to then visit the actual factory, if possible, and have quality / contracts down to a T.
Cheers!
