Okay,
Since Sup Forums inspired me to create a comic, I'll return the favor.
First off was that I went to comic conventions, and talked to professionals, listening to their stories. I befriended some, emailed them later, when I had questions.
Second, I looked around, and noticed what was big in Europe and Japan, but hasn't had mainstream success here. I looked at the stats, and tried to write an outline about that.
I wrote a 24 issue outline, and showed it to some creators. Pretty much everyone said it was 'okay' which is a polite way of saying forgettable. However, everyone liked a minor character, so I made another pitch with him as the main character.
I also shortened the issues from 24 to 5 issues.
Then I tried to find artists for the project.
I put a post on a website, and had 40 replies. I asked them to draw the main character by description. Only 20 did that.
After that, I picked the top 5 artists and asked them to draw a page from the script. I made them sign non-disclosures. I offered to pay for the page, but only 2 of the artists drew it.
I picked the artist the most people liked, but still give the runner up some work, from time to time.
After that, it was about 2 weeks of drawing character sketches, and altering them to make them work together.
We focused on the layouts, and slowly got the first issue drawn. After that, I hired a colorist, and a letterer.
Issue #2 was much quicker to draw, but the colorist disappeared, so the project was on hold for 3 months until a new colorist was hired, who had a similar style.
Issue #3 is now speeding along, everyone now has a good grasp of the series, and all changes are minor.
The most important thing is to get started.
After that, it's making sure you can constantly pay your artists and other workers.
It's a lot of sacrifice, any money not going to bills or food, goes to the comic. I forget what a social life is.
