i would love to help you:
if you have a story in mind already, then you need an artist.
an artist probably wont need you unless they express their techniques to you.
if you just ask,"do you want me to make you a story so you can start drawing"
chances are they wont
because you dont have an idea of their skills nor do they have any idea what you're going to write.
i dont know if im making myself understanable...
heheh
first of all, if you want to have artists,
you have to have the story halfway thorugh already, or at least an idea.
people who illustrate dont always have that "writing skill" that you might possess.
so if you have an idea, get a personal artist ^^
i can help
and i also suggest that you add in at least some reward if you really want artist to be interested
sorry for the whole paragraph ^^
but i hope it helps
