I know of engineering firms who charge an arm and a leg to consult on this kind of thing. I'm not sure how much help you can expect from the arduino forums, as it is definitely leaving the DIY space and going into commercial business
Yes it is commercial,
I was looking for someone who has done this before, which i appear to have found.
If this goes down that route i would be looking to pay the going rate.
Just trying to get some idea of cost before i waste time and money on a prototype that may go nowhere.
