You may want to consider reaching out to local running stores to see if they offer any training. I have worked with both local and online coaches, trying to run a Boston qualifying marathoning time, and local coaches can be better if you need more 1:1 contact (form analysis, group runs, etc...). Online coaches can be a mixed bag and can sometimes be wildly overpriced. At the very least a local shop may be able to point you in the direction of a local coach who can work with your daughter.
If you're looking for an online coach you may want to send a message to the folks at
Brooksee. They predominantly offer marathon and half-marathon coaching but I have been really impressed with one of their coaches (Paul Carmona) who has been incredibly responsive and has very reasonable rates. Alternatively the folks at
McMillan Running may be the go-to. I have not used their services but they were one of the front runners when I was doing my research into online coaches. They offer broad services (including 5k coaching) so they may be worth contacting.
Finally you will often hear from people that a coach is completely unnecessary and while I disagree with it, to an extent, it is true. There are plenty of great books available that offer easy to follow plans to get you to where you need to be. Even still, I value a coach for feedback and accountability (it is much harder to skip days on high mileage weeks if you know someone is watching) so don't let those naysayers dissuade you if you think a coach's guidance is needed..
