How do you find partners who are willing to do the work and not just be the "idea" person?

I've always been a high achieving, highly motivated student and worker, interested in ascending from the employee class to the employer class. My years of working as an engineer has shown that this is much more realistic and quicker to do by starting your own business than working your way up. I mainly want to do this because I want to legitimately make an impact on the world. I want to make a product that people buy and own it in totality, the design, the supply chain, the quality control, the marketing, the branding, the strategy, the market positioning. I genuinely believe in my ability to see things from a top level, analyze large amounts of information, and make reasoned decisions, all at a fast pace. I pride myself on not being a stereotypical narrow minded engineer with no social skills, but one who can actually present myself and my ideas well.However, I'm also aware that this describes almost every nerdy guy who is intellectually curious. Everyone wants to be Elon Musk. Everyone thinks that they have the perfect market of what VR could be, of what gene splicing should lead to, of business deals that can be made for self driving cars, or mixing social media and tech or whatever. Everyone thinks they see the trend. Almost no one is in a position to actually act on it.I'm proud of myself in that I think I'm good at actually doing the legwork. I have a product that I prototyped and patented. I do not come from a rich family and have not been in the position to bootstrap it. I spent over a year pitching to investors and got general feedback of "This is great, we won't bite until you start having sales though". The thought of actually getting this product out has motivated me for years outside of my day job, spending late nights programming, soldering, assembling, testing, driving to potential customers and pitching. I'm willing to grind through the "boring" parts of making spreadsheets and BOMs and testing from many suppliers and going through compliance testing. I attack all the busy work relentlessly, I love making progress towards my end goal.Launching the product is too much for me to do myself. I've looked for partners through my alma mater's alumni associations. I keep an eye out and follow up from contacts at pitch nights and venture capitalist nights. In these circles, there's a lot of BSers, a lot of people looking to get rich quick or screw you over. I've worked with some, and did eventually take on working partners, giving them equity in exchange for cash investment and them working on launching the product as well.However, there is a dynamic with them and other potential partners that I want to know how to get out of. Whenever I share the details, they always fashion themselves as the "idea" person. They're the ones with the high level vision, who can just perfectly picture how the product will sell, how people will interact with it. They'll do all the press, and shake the hands, and go to the important meetings. And I feel like they want me to be the code monkey, the greasy tech in the back room doing the grunt work.Of course I want to be the idea person. Of course I fantasize about being in a penthouse high rise office, delegating all my work, planning out new avenues of initiatives and R&D. But for now, I'm doing all the grunt work because this is a startup and somebody has to get us to making enough money to keep the lights on. I always thought that it reflected well on an ambitious person to attack the low level work while still keeping the high level work and goals in perspective. But for me, it almost feels like I get pigeonholed into being just a worker, because that's a lot of what I do at the moment.Is there a way to not fall into this role? I've never met a potential partner who seemed willing to really tackle the grunt work necessary in getting off the ground, only people who want to be the high concept people. If they exist, where do I find them? I'm starting to think that for my next business, it's better to just save up enough money to contract the grunt work out to people and maintain that contractor relationship and maintain my position as the top level person without letting anyone in. see hubwealthy.com/wealthy
