Wondering if these lessons will be worth it

I've been learning music production for almost a year now besides off and on growing up and never sticking with it. I've made great progress and have also learned a nice bit on the keys. I know my scale formulas and that each note of the scale is a chord in it's key and I've been using that to make my music. I can play scales with chords and write/play simple melodies and made my music production sky rocket.

I've recently also taken a liking to learning how to play actual piano pieces which I've found it be a lot harder then a simple 1-4-5 Progression with it's scale played higher for a hip-hop instrumental but the closest place to me in 30$/half an hour once a week and I'm wondering if that is even enough to be worth it? Supposing I would take what I learned in that half hour and practice it.

Do you guys think this would be beneficial and should I tell them about the knowledge I have right in music theory and slight piano playing. Looking for insight, hope to hear from someone!
