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.

If your friends can't invest their skills in you than no one else will.
And if you don't have a techy friend, then probably you should drop the idea. You don't know their culture enough to have them as co-founder.
