It sounds like you need someone on site for the server admini stuff. If that's the case, I may be interested as I'm considering moving back to the states real soon here. Let me know. I've done a ton of system and network administration of load balanced servers, routing using Netfilter, MySQL DBA and a healthy dose of PHP where I can slip it in, which is more and more often. The place has gone totally open source since i've been there.
