This type of question comes up regularly, and unfortunately there's no answer to it that's likely to be along the lines of what you want to hear.
If you have an idea which is commercially viable, then that's great. Really, it is! But you need to actually be in a position to exploit it yourself, and by 'exploit' I mean develop the product, build it, test it, manufacture it and sell it to customers. You need to do all that work yourself, or more likely, to find people with the requisite skills to do so on your behalf.
There are any number of ways to hire people to make the product happen. You might draw up a business plan, get a bank loan, and use that to pay them at normal commercial rates for their time. Or, perhaps you can offer them a significant share holding in your company, but that only works if you're all willing to take the risk and have something to live on in the meantime.
If you go the latter route, do bear in mind that the engineers developing your product are the ones putting in the work hours, contributing the essential skills, and handing over the IP which they've developed for the company. They are the ones creating all the value, and will expect a commensurate share of the pie at the end.
There is no organisation out there which will buy your idea off you for good money, then do all the development work and bring a product to market on your behalf. Moreover, the corollary of this is that ideas alone are completely worthless, and it's well worth taking a while to absorb that fact and get comfortable with it, because it's one of the hardest things to really come to terms with.
