Create logo, banners, and other marketing images for new podcast.

I am starting a new podcast that talks about things that matter (i.e. climate change) in a way that is helpful and approachable. I am in need of basic marketing help. I need help designing a logo/image for spotify and some instagram posts for when I’m ready to announce the launch. Nothing insane, I just want some 70’s-esque vibes and some creative ways to showcase the title “Thought Glass”. Thanks in advance!
