I apologize for my answer reading a bit disjointed. I'm limited to my phoephone at the moment, and it's making composing an answer a bit challenging.
Your question was:
will anyone actually want to work for us who doesn't need to be walked through everything and can do some things on their own?
I don't think that is a good question for Stack Exchange. We cannot predict if you will be able to find a developer who fits your criteria in your area. Even if a reliable answer can be found, it's unlikely to remain accurate for other areas. It might also not stand the test of time.
The only way for you to get your answer is to start hiring and see what you get. Nothing will convince your boss of the error of his ways other than some real information about real applicants.
Popularity of a question is not always related to its suitability. To me, this felt like a "what salary should I expect" question in reverse --— ultimately, too localized and hypothetical.
