I'm probably misinterpreting your requirements, but you should look into Korean IPS monitors. They're generally very cheap, are far better at reproducing colours than standard LCD monitors, have higher pixel densities (1440p@27") and can often be overclocked (90-120hz). The best deals are usually on ebay, shipped from Korea.
But it is an entirely different manner when your purchase has to be approved by a pyramid of bureaucrats and more importantly, buying things at online auctions (eBay, gasp!) or even otherwise (amazon) takes weeks to be approved. And oh!, we need five of those monitors to start with (and they better work!).
