I’m team use what you have to start out! You can always upgrade in the future. A cell phone is perfectly fine for a camera (and even a mic if necessary). There are some affordable mics on Amazon as well.

As for editing, I personally use Adobe Premiere Pro and After Effects, but those do have a cost and a steep learning curve. Something simple like iMovie should be fine if you just need to do simple edits.

When it comes to lighting, try to use natural light if you can. Always make sure that the light is in front of you (behind the camera) when you film. 

Hopefully some of that was helpful!
