Advice on Freelance Writing / Pitching?

Question

I am looking to start freelance writing while I look for a permanent writing role and wanted some advice or tips on the best way to start freelance writing and pitching!

At the moment I am a contributor at an online sustainable magazine and have built up a small portfolio of work which can be found here; https://daisywallis.journoportfolio.com/

Currently, I have experience writing on fashion and sustainability but would love to write some more lifestyle-based pieces in the future.

Thank you for your help!
