One example is Logic Product Development. (My employer - shamless plug) We do exactly what you are asking for. Sometimes (when everything is custom) it is expensive. Sometimes it is not. There are many other product development houses out there (also called contract engineering houses) that can take your prototype and turn it into something that can be mass produced. You'd then have it manufactured at a CEM (Contract Equipemnt Manufactuer) either here or overseas.

I do serial port GUIs with LB all day every day. http://www.libertybasic.com/ MUCH simpler than VB,.NET, C# or almost any of the others, but still gives you a complete GUI experience. The helpfile and exapmle code make it trivial to cook up code quickly. Try it out -
