Truthfully, you do not need three routers, but only at worst two (assuming coverage issues don't dictate access points).  I have for example a cheap Tenda N60, which can be configured to set up guest access with a separate IP range and AP isolation.  There are other available router/firewalls which perform the same deeds.

For the additional IP range, let me note that if you have 50 users on any router, throughput is going to be severely limited.  In fact for school usage you likely will need more than one normal business level internet account gives.  I'm sure there are folks on here with extensive experience dealing with such issues, who can detail how to prepare adequately for that.
