Actually, I'm more than qualified for your position on the technical side, but if you want an active clearance with that diverse a skill set, then you're severly limiting your pool of applicants. It's a hassle to jump from cleared job to cleared job, and staying in the commercial sector too long makes it difficult to reactivate easily.
But based on the tone of your statement, and that you apparently want to cut corners by hiring one person with multiple specialties who is also already cleared tells me that you would be a PITA to work for. This may be why you aren't getting many good applicants. I'm continually amazed by the number of IT managers, some with many years of experience, and some who are close friends of mine, who really don't understand how little they know about managing IT. You may be one of them, but I don't know you.
The biggest mistakes most managers make are assuming that it's all about the money, and that the negotion is all on the employer's side. Hint: if you have nothing to offer me besides money, then it better be a LOT of money, and I better be in the mood to put up with your bullshit.
I work in IT because I want to. I like what I do so much that I have often worked for below market salary just because I liked the people and managers who I was working with. The problem is that most managers are too clueless to realize that their most important job is functions are to be a crap deflector and resource provider. Get too much crap in the gears and the machine stops. Don't provide adequite resources, same thing. Your team leads, if they are any good, will help organize the team. Its a lot like driving a boat. You have to correct issues before they become problems, and back off before you oversteer. All of the good teams I was on ran that way.
