Hi,
Have a look on Skype, you can find alot of groups that will offer practice english for nothing.
Usually school age students interested in pen pals (chat pals) and plenty of others...just use some caution but generally pretty good.
I am sure there are some user groups for this on skype? I've never looked....but I have heard from others they are out there...

I would happily pracitce english with you but I am not there any more
