I have an idea/invention and look for a real investor/industry to take it to the next level?
That's because ideas are ten a pennny, and real engineering is extremely expensive once you have to pay professional engineers and contract manufacturers. If you can, produce a working prototype of your invention, then look for a venture capital company. You also need a NDA form for them to sign, plus a detailed business case for the invention. Just getting the paperwork together is probably going to take you a few weeks of effort.
