I need a host that has virtual servers. Im really not sure if thats what there called, but i heard some other guy (http://www.webhostingtalk.com/showthread.php?s=&threadid=17007I) on this site describe them by that.

By virtual server i mean "a server that allows the user to edit config files on the server, but isnt a dedicated server, because it serves more than one virtual site"

So for that confusing little bit, but if you know what im talking about? please help!

I know about superb.net SPS hosts but it requires a minimum of 6 months, and im looking for something with 1 month

Find an Ensim ServerXchange provider and you will be able to get a Private Server (ensim's brand of virtual server). Ones that I know if are.

forsite.com
superb.net
cybertitannetworks.???
.. I'm sure there are many more...
