Sorry to hear about you not getting onto TV. You seem industrious enough though, so it'll work out in the end for you...
Happy to hear that you're keeping production close to the market. Have you considered the environment angle when marketing it? Surely manufacturing the product close to it's intended market has less impact on the environment when it comes to (especially) transports than it would have if it was made on the other side of the globe? I'm also quite certain that you brits use methods less harmful to the environment in your production processes than, say, the Chinese.
You could also push the patriot angle on the packaging on the items going into stores. "Made in Great Britain" or something
I mean, I know I am willing to pay a slight premium for a locally made item over a foreign made product of comparable quality.
Just a thought.
