Hiya,
I specialise in this sort of cleanup, security, optimisation type activity. I'm a Linux systems admin & PHP coder with 15+ years experience.
My existing customers say of my services for example:
"Thank you, you're a God-send".
Josh Strike - Strike Sapphire
"Thank god for you being available, dont know what we would do if you were not around."
Matt Norris, Strand International / Easy Play Poker
Oh, and I'm also a member of the Association Of Independent Computer Specialists (AICS) and am bound by their Code Of Practise.
For my bid price I can give you 2.5-3 hours of my time to look at cleaning this up. More time available if needed, and I can provide an ongoing management retainer to stop it happening again as well as the other activities you mention towards the end of your job spec.
Yours,
Kev Green,
oRe Net.
