Thinking about creating content for others. What should I know?

Hi everyone
I’ve been running a few of my own social media channels, including one in the sports and tennis space, and I really enjoy creating content.

Now I’m thinking about offering this as a service to others. That could mean helping with posts, short videos, or turning blogs and notes into content for Instagram or TikTok.

For anyone who’s already doing this
What should I be aware of before starting?
How do you usually find your first clients?

Would appreciate any honest advice or experience. Thanks.
