Your design has to funtion, if it doen't it isn't considered useful by the USPTO and you can't recieve a patent for it. Be as complete as possible, and make sure you record everything pertinent to the creation and functioning of your invention.

There are people who will be happy to help at all stages of developing your invention. These people charge for thier services, but they get the job done. You may consider searching for rapid prototypers on Google, or drafters, designers, engineers. Anyone you find who charges you an honest fee to do an honest job is most likely a great place to do business with.

Avoid something for nothing outfits, you don't want to be added to the list of inventors that feel they cannot be trusted. It will cost you more money for more help, but that's capitolism for you, the very same system you hope will make you a tidy profit on your invention.

The internet, with the use of a great tool like google, is the inventor's largest catalog of resources.
