The good news about your VolleyPSA's situation is you have time to figure all this out. To make a firm evaluation right now is not logical because as a freshman, she still has so much volleyball development ahead of her.
As your daughter is developing her skill sets, it is important to compare. Compare how she looks versus other older players, compare how she plays versus a big city club player when you see a bigger club at a tournament. As she gets older and more developed, at a big tourney, go watch the same courts where the college coaches are hanging out recruiting and see what these players look like. You have to take a look at what other players her age and her position look like; and not those players just in your back yard, but players out of region and out of state when you see them at tourneys.
One thing I will say, is that 5'10" will be short for a DI middle and a bit small for a DII middle; but could do well DIII or low NAIA. Is she done growing, is she able to do all the footwork attack patterns of a middle and not just a high 2 in the middle, how is her block/attack jump, what is her hand position when she blocks? All questions which college coaches will examine when they evaluate her.
You need to let her develop her skill sets, and as she develops, then you start to compare her to others in her position.
As for club coaches, it is not their job to be active in the recruiting process - their job is to train and act as a positive reference during the process. This is one of the 'myths' I explain during my NCSA Volleyball Recruiting Education Talks.
Your job is to be active; use technology to reach out to collegiate coaches as I have advised on this site and in my book. You can overcome your small town/small club geography by using video and technology to generate interest in your daughter's ability, provided you are reaching out to the correct level; reaching out to the correct level is allowing your daughter to develop, and determining how she compares against other players.
Good luck and keep putting in the effort!
