Small business startup using X-carve, advise for Business Classification codes

Hello members,
I need some help please, trying to register new business (sole proprietor)and need advise for Classification codes.
Standard Industrial Code
I will be using my x-carve to produce anything from signs to seasonal items and possibly artwork, but I am having a very hard time trying to find the correct codes.
Any help you can offer would be appreciated.

Did you figure this out? I am thinking of doing the same thing, plus I already build guitars.
