Sorry if this will be too harsh, I'm trying to be helpful and honest.
Something is fishy here. In another question you said you were "carefully protecting" your idea. I think that is completely counter-productive, but I also don't see how would any investor approach you, if you have no product yet, and you don't even advertise the idea. Furthermore, investors don't care about ideas, they want to see either traction, or a proven team, or both. If I had a dime for every time somebody told me my idea was awesome, I'd be a millionaire. There is a world of difference between a guy who claims to be interested (usually means he's polite or tactical) and an actual customer/investor of your company. Never confuse these two.
Also, there is no such thing as the "idea guy". Either you have useful practical skills for a startup, or you don't. If you are non-technical, you'd better be a great design/sales/marketing guy, or at least have the will to become one. Some essentials on the topic:
About the tech co-founder, it is extremely hard to find a good one, because most coders don't need or like to take risks, and also because "idea guys" keep pitching them 24/7. Demand is an order of magnitude higher than supply of tech co-founders. Your only chance is to find someone with an entrepreneurial mindset, who falls in love with your vision. This took me 2 years. Quite obviously, under these circumstances you have to be very fair about what you offer. Equal equity split is the minimum, I'd say.
But you don't need a tech guy to validate an idea and generate traction. Why don't you just put together a landing page with launchpad and mailchimp, and start getting subscribers? Why don't you get out and talk to potential customers? Why don't you start a crowdfunding campaign to see if people are willing to pay for what you have in mind? After you've done all these things, it will be a lot easier to find a technical partner, or even an investor. Your job right now is to show what you can do, and not to find somebody for the stuff you can't do. Somebody once told me that you don't find your co-founder, but rather earn it. So start working!
