Many people want to make a product from their prototype.
Problem it is not that easy and you might need mentoring.
Today I saw this link of Patrick Andrews - http://www.musetuners.co.uk/services/one-to-one/inventor-mentoring/
For those who need that little extra.
I know Patrick for some time from his invention of the day site - http://iotd.patrickandrews.com/
Patrick is a creative person with a steady output of ideas. Imho he is capable of good advise (always depends on the problem), knows his way in the patent world etc.
