Good luck with your search, fella!
However, if i can play devils advocate...
This is the second time i have given this advice on here today and i am sorry to keep repeating myself.
But you will have more luck finding a partner if you are paying....honestly, something is better than nothing.
I know that is a kick in the nuts, but sadly it works.
I am speaking from experience here...as a writer myself, it is hard finding a artist partner because sadly "possible" back end payments and royalties is a tough sell.
It takes a decent artist at least a full day to do one page (just pencils), so to put it in context...would you work a full five days at work for a "potential" unknown amount pay day that you wont see for 6-12 months?
John layman paid Rob Guillory out of his own pocket to make CHEW before it got picked up and he is a seasoned pro.
Even The Chief pays his artists collaborators out of his pocket...
What helped me was start thinking in "pages" rather than money to help me save up.
"i really fancy a pizza tonight, hmmmmmm, actually the cost of that is the same as 1/4 of a page of comic art, i'll cook instead!"
Instead of going to the pub with my mates and buying three rounds at £5 a pint (its expensive in London)...i got a couple of beers from the supermarket and went home and wrote...while getting smashed!
Three rounds in the pub is half, if not two thirds a comic page!
Seriously it works, its how i saved up my cash to pay my partners and it is crazy how quick you'll save up for five pages.
Plus, as well as making the artist partner feeling appreciated, it will also give your partner more incentive to finish.You might be lucky and find a AMAZING artist to work on your story...but he/she is always gonna put paying work ahead of your because they got bills to pay.
..again from experience.
The original artist on my comic CHUNKS had the script for a year...i didn't see one page...couple of character designs and a pin up...had to take paying work.
So, i went away, saved up, paid Cris and we are on #3
I hope that helps?
I'm really not trying to be preachy...i just don't want people to make the same mistakes i have!
