I want to print some rusEfi stickers and I need them to be waterproof. I've tried something like Adhesive Full Sheet Labels - the ones you use with a laser printer - but these did not like being outside.

What are the keywords I am looking for? Is there anything I can do with a laser printer or do I need to order them somewhere?

Check with businesses that do business cards, signs, banners, maybe even t-shirt, custom hats, uniforms, trophies, et cetera.
One of them will know someone in the area or possibly online.

The more you add, the more they cost- multiple-color, laser cutting for custom shapes.....

I've not been back home in ten years but here in Australia I'd go to a vehicle sign writer. They do them in a plastic film and lYer for multicolour.... The truck company I worked for got them made all the time pretty cheap considering, or reprap cut them cnc type??

I know there are companies like http://www.cafepress.com/ they process credit cards, make and ship product. What you do is make designs and sell, they deal with all the other business bits that artists often don't understand or do very well. The down side is that they don't seem to do stickers. The do other swag, like coffee cups, T-Shirts, bags, laptop skins, ect. As well technically minded folks will consider the convenience to be expensive.
