I fulfill all of the requirements. Although, how dependable do you need me to be? Say on a scale of 1 to 10? Other than that, I do not have squeaky voice(i don't think) I am over 14, i have skype: Marco_the_Pirate. I have a mic, i know how to use some of voxelsniper(i can learn) but i know worldedit really well. I could be more mature than you or not.... O_O I think of myself as a good builder and I kinda know plugins...
I'd love to help you out with your server.
