Elastic bandwidth for a rural area

Hello I know somewhat about networking. We are located in rural alaska, which bandwidth is insanely expensive and limited. So at my school we have 100mbps up/down aggregate. We have over 450 students and about 50 staff. I want to use our bandwidth more efficiently and give priority to certain apps at certain times.

The problem

Without going into the weeds, we have 2 different vlans that share the bandwidth, student (very limited) staff (mostly open). We allow one person to be able to take the whole bandwidth if they can. The problem is that sometimes unknowingly they do or many users just bog down the wan connection.

The solution we have right now

We are constantly monitoring the network, we have some QOS for VOIP programs, and try to constantly open and close yt, fb, and different video sites due to need. This gets cumbersome for tech staff and inefficient.

The solution we hope

Is there a way (it can be expensive) that the network can be elastic, scheduled, and give priority to certain ips. So when school is open someone can take the full bandwidth but if other devices show up it splits the bandwidth evenly, So we are taking advantage of the whole pipe the whole time. And then when the many people jump on split the network evenly or in a set order that we desire. How do you guys suggest this can be done, in the router or firewall side or do we need other servers or appliances to do so. We are thinking of hiring this out, but every company has their own solution.

TLDR: BAndwidth is only 100mbps for 50 people, is there a way to make the network elastic to use the whole pipe or less when need it?
