Based on your email, I would suggest the following:
1. Expand your collegiate options to DII and NAIA. Many, many DII/NAIA programs also highly value academics, and unlike DIII, their scholarships include athletic monies. Remember, that DIII only can provide academic (and need based) scholarships. Better to expand your outreach efforts now, so enable better choices next year. I present an updated Recruiting Plan in Inside College Volleyball, and for maximum exposure, it is hard to beat the support of NCSA Athletic Recruiting!
2. Hoping that there are more than 2 club teams in your region, when you go to tryouts for next year's teams, absolutely be clear that your daughter is trying out for Outside Hitter and will not play anything else. Make it clear, but friendly, that this is because she will be playing Outside Hitter in college.
3. If no club can provide that promise, then don't play club. Better to use that club money for private lessons to target specific skill development, and to use it for unofficial visits, than play out of position her senior year.
4. Mentally flush away this year's club experience. For whatever reason, your club directors were more concerned with returning players and other families than yours, which I have seen quite often in the club world (so don't think yours is an only situation). It is spilt milk, you did everything correctly, your daughter was a good team mate, so take the high road and move on!
5. Get back into the high school gym this summer and make some new skills video, which is not rushed - Actually, do it now while her skills are still fresh after club. Video will be key in your outreach efforts.
6. Use this new video, and reach out to a bunch (I mean a lot, many, mucho, lots, etc) of schools - College coaches recruit talent. If they think your daughter can help them, then they will recruit your daughter no mater her club situation. Again, reach out to the D2 and NAIA schools, because a 5'9" athletic OH who can play back row will be attractive!
Good luck and hang in there!
