Need some advice please on a new server, what should I do?

G'day,
Reason for this question is I am not too sure what should be setup on a unmanaged server and what should be already setup ready to go.

I can't get through to tech support for some of my questions;
ie:
----- Transcript of session follows -----

>>> DATA
<<< 451 Temporary local problem - please try later
<[email protected]>... Deferred: 451 Temporary local problem - please try later
<<< 503 valid RCPT command must precede DATA
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old

Anyhow I feel that I should continue giving with this one and give it a good go so my questions are;
1) Is there a Company who can perform some tasks (for a fee) to setup;
The following have not been installed;
Apache Webserver / FTP server / DNS / PHP / Mail / MySQL

Aww my head hurts cause I am on other unmanaged server where I these simple things are already installed..
Good thing I can say is that I learnt about the command yum today...

Hosthead Guys, I miss you guys and I think I know what I will do this week!

Thanks, and am open to any kicks in the gutt right now guys so fire away!
