If you have a new or fresh idea to present, we are certainly happy to consider it and to try to help you with it if we can. There are gradations of submissibility. The lowest and most difficult is the concept that has never been executed, not even in prototype format. For example, people come with food concepts who have never prepared the components of their creation, not even in their own kitchen, for their own tasting. There is little that can be done with a concept that is at such an early stage.
Someone has to test it.
Either its creator will do so or someone must be hired to do so. Someone has to take a picture of it. Someone has to prepare some kind of written statement of its purpose, its manner of production, its suggested manner of presentation. That is just for openers. Someone will contact us with a business concept, but they have never researched it to see whether anyone else is already doing it or something like it.
