I have an HTML5 cross-platform, cross-device, cross-os poker engine, supports up to 100,000 simultaneously connected players via Websocket on modest hardware, offers revolutionary "Provably Fair" play, the numbers are generated without the need for a physical RNG that works on the principles of quantum mechanics so it saves you another 8K. it is ridiculously easy to integrate with existing websites.
I can offer ONE license for ONE server (one instance of the server app running) for a low price, I am also likely to give you updates for free as I use the same engine myself.
