I have a multi-media publishing platform (image, docs, audio, video, quiz, drag drop games) which was made for my own use using PHP4/5 and mySQL on Linux. I have a pop3 email system. I have plug in Word press. Everything is on two hosted servers. My root level access to servers is by webmin/usermin. Parallel Plesk is provided by host company for server admin. I have several domains pointing to this set up. I need a professional for a few hours every week to maintain the system including:
1) Email whitelisting
2) Email security maintenance from malware, spam, virus etc.
3) Server management
4) Server management operating system and admin updates maintenance
5) Occasional bug fixing of PHP/mySQL software system for publishing
6) Very rarely a little coding to develop new functionality in the system.
