In that case you might want to take a look at the iFixit instructions for removing an optical drive, and taking out a stuck disc, ChAz.
The process for removal differs a little from model to model - for the late 2007 / early 2008 models you will find them
HERE (the same site has specific instructions for earlier and later models too, so if this is not what you have then take a look around).
Once the drive has been removed the process of removing the stuck disc is reasonably simple - see
HERE.
If you don't feel confident enough to undertake the task yourself, and in the absence of any way of getting it to an authorised Apple repairer, then if you take the instructions to a good local notebook computer repair shop they should be able to do it for you without too much risk.
I see a couple of possible (probably unofficial) Apple places in Lagos mentioned at
http://www.nairaland.com/nigeria/topic-376297.0.html though.
http://www.ishopA.com/ might be worth a look too.
