Welcome,
Query, care to provide some background allowing you the expertise to design and build not a home project but to build multiple numbers of such a device, PE?, ME?
Appropriate, drawings designed, drawn, peer reviewed, approved?
Appropriate testing through the design, prototype build, prototype operational tests, final build, first article operational testing, then formal testing in various conditions all the while documenting, and accomplishing ECOs as appropriate under CM control throughout the entire manufacturing process!
Finally, since you have a named product, publicly produced a demo video, one presumes appropriate patents have been obtained to protect your investment and investors!
Oh wait, is this the same product citizen asked about in 1/2/13... in holsters and accessories ~ holster that racks twenty eight posts about the product.
So OP still sticking to your story you gave grape YOU just made a couple and seeking advice BS now stating "the supplier" ?

Added... shame as loss of one's personal integrity is something that is difficult to ever recover and lowers oneself to the level of a used car salesman.
