You need to be in a group to raid - usually a large group. Raid groups are usually organised by guilds and guilds will always try to have only guild members or friends that they know are good players in their raid groups.

If you've never raided before and/or haven't raided much, no one is going to want to put you in their group as raiding is a big time investment and one poor player can really stuff it up. People will avoid pikcing up randoms.

You should try to join a guild that accepts begginers and does low level raids. Look up the guilds that are on your server and ask if you can join and tell them that you're really keen to get some raiding experience.
