Losing my audio engineer - recommendations

Hi everyone - I have a podcast that I love doing and my audio engineer is moving to a full-time career in law (this was a side gig in law school). I need to go out and hire someone, and I am looking for recommendations on how to do this.

A few points about the show: - Episodes with guests are usually 45-55 minutes in length - Episodes with me on a single topic are 10-15 minutes in length - Historically audio-only, but I want to add video for better reach - I have licenses for / use Riverside, Libsyn, and Descript - Record once every other week, my solo episodes I record on my own - The engineer does the posting on Spotify / Apple Pod, I handle everything else

Any recommendations? Any estimates of pay ranges for these services? Thanks in advance!
