Arrange a portfolio. Take your best samples and place them in a binder or notebook between clear plastic sheets. If you have published comics, place them at the front of the book with the name of the publication and print dates highlighted. Include a typed resume for reference.
Concentrate on the visual appeal of your work first. Whether you are toting samples around to publishing houses, clients or printing the work on your own, be aware that style and flash sells. Work to improve your illustrations, and pay special attention to drawing urban landscapes. Think of Gotham City in the Batman comics and other depictions of rugged cities.
Be original. Remember that superheroes and space commanders don't populate every comic book out there. Draw characters from the heart, and stay true to your vision. Comic book characters can be realistic, sexy, tragic, funny and heroic-anything you want them to be. A well-conceived story will always find a market.
Approach publishing houses and comic book editors with your portfolio. If you draw in the traditional superhero style, try Marvel or DC. Check the submission guidelines for an existing line, or submit your own original story. Other independent companies like Dark House may be more open to quirky styles.
Do it yourself. Depending on time and resources, you can put out a photocopied comic zine or a more elaborate, perfect bound book. Consider getting financing and a partner to help you if you decide to print a large number of copies. Use print on demand options if you have little start-up money or want to test the waters first.
