One of the most common conversations at the bar must be "I had an idea for that....". The story's inevitable ending being that the idea remained just that. An unfulfilled dream that could have changed the World!
The stone work above from 'The Devil's Den' near Marlborough was someones idea, and at the time they must have thought it was impossible, but there it is.
So many of us have ideas. Indeed every business or organisation started as one, bar none. So it is safe to say that if you have an idea, there is every chance of it working if it is good and fulfils a need or requirement.
So run with it.
Use what resources you have available, be it time or money, and flesh out a plan of how said idea might become reality. A plan written by yourself or your partners is no contract, not a binding agreement, it is just a plan.
Then go about making the plan work bit by bit, you may need help with that plan or the bit after (we can help there but that's another thing all-together) but there is a process you can follow at whatever speed you want.
Sure you will need some help and luck upon the way in terms of the breaks, but you don't need luck to follow a plan. So make the plan and run with the idea!
