Been doing plenty of videos for my clients where I mix and master their songs and explain everything I do using my most trusted plugins and techniques.
I also compare the song to strong reference songs and see how it does compared to them.
On top of this, the producer can ask me questions relating to mixing/mastering/production and I’ll cover all his Qs.
Rate for this: 50 EUR per hour used (+VAT if in EU).
Love my job. Love getting geeky and nerdy. Pretty much more than a full-time thing now with mixing & mastering included, but I love it all.
