Well, it depends. Is it a small role? I currently have a few projects I need to work on and can only participate if the role does not have a huge amount of lines. Also, how long time would you give me to record them? I can consider a bigger role if I am given plenty of time (more than a month, for instance).
Also, can you please provide me some info on the project, since I am not that familiar with Final Fantasy (I guess that it's the project you're talking about).
I'd like to scout you to play an extra in my dub, if you'd be up for it
