I've got several ideas for new products that I think might fill various gaps in the market. However, I'm unsure where to start. I'm not an engineer, nor do I have access to facilities to create prototypes for any of these ideas.
The only way around this that I can think of is to go to a large company that makes similar products and ask them if they are interested in my idea. But of course, since all I have is the idea, once they know what it is, good or bad, there's no point in me any more.
Does anyone have any ideas about where to go or how to go about getting prototypes built, etc.?
My question relates specifically to the UK.
Thanks for all the answers (especially the comment about Hackspace - although I'm not near London), although I think the question may have appeared slightly misleading. Many people said: "Ideas are fine but you have to invest in producing one once you have a customer!". Okay, so say I have a customer lined up and I have money to invest, how do I get a prototype built? Where would you go for this?
Let's say, for example, that I've just had an idea for a super efficient bicycle or something. How do I actually go about going to a place and getting one manufactured as a prototype?
