I'm a bit confused. Are you looking to develop a new story from scratch with someone? Are you seeking to be the artist and co-writer, or some other role(s)?
If the above assumptions are correct, could you provide more info about what you can and are willing to do? I mean both content (mecha? nudity? romance? scenery? what are you willing and unwilling to draw in a comic?) and quantity (how many pages per project, and how often?). Your tumblr mentions that you're going to uni, so I imagine you wouldn't be able to commit to the kinds of comics many would-be writers here want to make.
I'd like to know a few of these things as well. Particularly scenery. Backgrounds are the bane of many artists (myself included).
It's no that I can't, it's just that I don't like to. Also it's sort of hard to get it to look right with the people in them...
