Buffy the Vampire Slayer ATC

I want to do a series of Buffy ATC's, but I don't know how to go about it. I don't know if I should just make them myself, or find a swap online and do it through that channel. I want to get started on these, because I have a few really good ideas. If anyone wants to give input, let me know. Like A is for....B is for and so on. Help is always appreciated!
