I am a Mechanical Designer by occupation and here is just my 50c.
Learn how to use Solidworks by watching tutorials. Make a model, drawing, whatever you need - bring it to the local engineering company and ask if they can make a prototype for you. You could always hire a designer on Fiver, but if you can learn it yourself - it will be easy for you to make changes to the product on the spot and better communicate what you want your prototype to look like to a manufacturer.
There is a good thread on a forum from Vick on how he manufactured his own brand of sunglasses.
Hope it helps!
