If you have a great idea but no money to turn your invention into a product, you can submit it to Quirky.com and get help from a crowd of designers, writers and more to get it ready for submission. All the ideas are voted on and the top ones are submitted to the weekly evaluation. If they get chosen, the team from Quirky puts it in front of people who can turn your idea into reality.
You will get a share of the profits and so will the people who helped you, so if you don' t have an idea yourself you can always join a team working on someone elses idea. If you have a skill like 3D rendering you can browse the projects and choose the ones you want to work on.
So whether you are an inventor or have the skills to help make the submission so good it gets chosen, you could help bring new products to market. If your idea gets chosen for the fast track to manufacturing you could also earn money each time it gets sold!
