4x4 Bumpers

What can I do to make a custom bumper for my truck 4x4? How do I arrive at a plan that manufacturers can follow? I have an idea of what I want it to look like, but I have no idea how to transfer it mechanically on the paper.

Go to the pirate 4x4 ago bumpers as you can decide that one of the suppliers already do exactly what you want. Also, if they have not pictures great and you can have a good idea and image of what you are looking for.
