I'd pitch to a few, fella.
But if i'm honest, i'd concentrate on one series at a time and have more than just a few pages done.
Say a publisher comes back and say they wanna see more....your are gonna have to wait for the artist, letterer and colourist to work their magic...how long is that gonna take....a month?!
if you get a YES...you wanna be able to be ahead of the curve.
I submitted TRANSFER to a few publishers....most i didn't hear back from (which you wont)...or at least not yet...seven months later...
One did like it and asked how many issues i had ready...at that time i only had the one...so they passed...
Make the comics because you wanna make them and get them out there.
Have getting it picked up by a publisher as a goal, but not the only goal.
Look at Ryan Ferrier for example, he just went out and made his series D4VE, with MillarWorlder Valentine...i think they get two issues out there...THEN it was picked up by IDW...
Plus, you weren't rejected...your story just wasn't picked....this time...like the rest of us.
There is a world of difference.
