Can't you host a server? I think we have someone who can, I'd have to check though.
I've checked EGS server (on which I have 30 ping, so I'm guessing that the one with good ping for you too), and you can change the settings to TDM, and extend time limits and kill limits. It would mean that we would have 4vs4, but I think thats realistic for how many we could get anyway. We will probably have more than one match anyway, so you can always rotate players.
