To assist her in the collegiate process, you have to empower her. College coaches are not too keen on high school coaches leading the effort because they want to hear from the athlete. If you do all the reach out, my first response as a coach is, why am I not hearing from the players or parent.
Sit down with her, figure out her comfort zone with regards to academics, distance from home, reputation of the program (will she play right away or sit for a year or two), big city/small city, big school/small school, etc. After you have a general idea, then start her emailing programs basically saying "hello, here I am and come recruit me!".
Don't hesitate to use NCSA Athletic Recruiting's Free site, which can serve as an excellent resource for NCAA rules, along with researching college programs!
As for no-club volleyball; it happens and college coaches understand that sometimes club just is not a possibility. This is where video is your biggest resource; as you are the coach, she will have access to a gym/net/balls, so she can shoot multiple skills videos. And videos today are silly easy because of smart phones/tablets and youtube. Shoot it, edit it, upload it and send out the link to college coaches.
Hopefully your city is big enough that she can jump in with low cost adult leagues (indoor, sand, grass) to keep her skill sets up. In some ways, playing against adults can be the best thing that happens to young players because they can pick up so much!
Good luck and just take the challenge head on!
