Free Minecraft Server 24/7 (Up to 3 servers and an infinite amount of RAM)

Hmm, doesn't seem really real.
There is no way this could be free.
Just buy an good quality server from any host (NOT SERVER.PRO)
It doesn't cost that much on some hosts.
Maybe you can even get a VPS and install your own panel to create your own minecraft servers.
That's the way I do it :D
