You can start by building a strong online portfolio showcasing your best comic work. Then, actively network on social media and comic-related forums to get noticed by potential clients.
Pricing comic commissions varies. You need to consider the level of detail, the number of characters, and the style. Also, think about your reputation and the target audience. For beginners, it might be lower, but as you gain experience and build a portfolio, you can increase the prices.
You could also self-publish on platforms like Amazon Kindle Direct Publishing. Earn money through royalties based on sales. Another option is to enter writing competitions that offer cash prizes for winning entries.
Getting paid for fanfiction can be tricky. You could explore self-publishing options and promote your work through social media to attract potential paying readers. But be aware that many fanfiction works are subject to copyright restrictions, so make sure you're not violating any laws.
