Part-time Linux Network Administration

project is ongoing network administration for a small company located in Jakarta, Indonesia. we require assistance in setting up our linux servers for things such as web hosting, caching, and possibly as a .id domain-registration centre. we require that all installations and changes the system be documented so that we know what has been done, and how to duplicate or modify it should it become necessary. for the first 2 months i anticipate it will require on average 2 hours attention every day. we would prefer someone who can work during our jakarta working hours (9-5, +0700) to enable effective communication. we currently have one HP proliant server in our jakarta office, along with 24 workstations. there is also a separate sub-server as a DNS cache. connection is a 2Mbps dedicated line. each of our branches in bali and batam have servers. files and email are synchronised using unison and offlineimap. our web server is a VPS located in singapore. we host dozens of sites there, mostly our own. we are currently tendering to become a registrar for .id domains, and should this be successful, we shall require someone with a thorough knowledge of domain registration processes and procedures. i hope this is a clear enough picture for you. please let me know if you are able to assist.
