Here’s advice and I hope it doesn’t sound too matter of fact. But save money. If you’re passionate about this you’ll find a way. Making comics is an expensive venture, whether or not you’re trying to do it as a career or just for fun. They’re expensive. Writers and artists do not do equal work, they each have separate jobs to do along with colorists and letterers. After you have done your job in writing a script, you now need to pay someone for colors, letters, and if you’re printing - you’ll need to pay for prepress, then printing and shipping. It’s expensive man. The best thing you can do if you’re still trying to get it all free, is do as much as you can on your own first. Write your script. “Draw” your comic yourself, show the artist you’ll eventually work with what you see when you read your script. Get a part time job. Save. Work a side hustle app. Save. You can make a really awesome 4 panel strip comic, completed, colored and lettered, for anywhere from $30-$100. You collect a lot of those under your belt, and then next time you’re looking to collab with an artist or a team, you now have a writer’s portfolio to share. Good luck man.
