Hi Manish,

Your email is contradictory. If you have a shared server you will not be doing any installation, config or admin as it is all taken care of for you. Maybe you are referring to 'virtual hosts' where you essentially hire a VM machine portion of a server, in which case you get full root access to do everything with. The problem with shared virtual hosting is usually limited CPU and limited bandwidth.

Just scan for 'virtual shared hosting' or 'virtual private servers' for this.

uk2.net do dedicated servers for £50 per month, with very excellent bandwidth

All web hosts are crap at one point, usually when they have a server outage and this can cost you a whole day or two. If that is a problem for you, I would also recommend outsourcing your DNS (someone like ultradns) for about £20 a year and hiring a second server, from a separate provider. Your DNS settings can be changed to 10 mins time-to-live and if you have a problem with server#1, change the dns to point to server#2 (and of course copy all your web files from your regular backups to server2) and you will be up and running again in 15 mins.

hope this helps.
regards,
Antony Penn
