I was very recently in your position.
Remember, an idea is worthless. They have people asking them to build things for equity all the time. You have to compete with these people. If you want to attract a tech-cofounder you have to show value. No one is interested in a one-side partnership where they have to do all the work and then give up a large portion of any profits. How are they going to know you can bring anything to table if you have nothing to show?
After I had identified a potential pain point and thought up a solution, this (in order) is how I proceeded.
I enrolled in a relevant classes (business fashion/intro to entrepreneurship), wrote a business plan/financial statement, figured out the features and how I wanted the app to work, contracted wireframe mockups, raised money from family, hired a lawyer to form a corporation, had the graphic design done, had the front end done.
It took a year and $4500 before I finally found my co-founder.
All the stuff had to be done anyways and it was stuff I, as a non tech-cofounder could do. After I met my technical co-founder we spent a week transferring knowledge (after working on it for a year, i had a lot to say) and now he is coding away.
Also everything took way longer then I expected.
