i don't mean for this to sound rude, but this is ext 2 english. you can't expect others to come up with ideas for you...and you don't want anything that has worked in the past. originality is the key.
and you need to find your own idea, this is a highly personal course. pretty much everyone here will tell you that it only works if your work is what you want it to be, things start to go wrong when you let other people dictate what you're doing.
you have plenty of time. muck around with what inspires you. read, write, whatever. you can come up with your own idea, and if you can't then maybe you should rethink doing ext 2.
