Hello! @USL_Pony
I personally don't play the openings you mentioned (except sometimes the opposite color of course) in classical games, however, that doesn't mean I don't understand how to play these openings. I have plenty of opening material I can share with you, and have the understanding for the structure/opening ideas to help point you in the correct direction while still giving you deeper theory if that is what you're wanting.
If you are worried about how "close" our blitz ratings are, then I can assure you I can still teach you plenty. I have had students in the past, and current who are even stronger then you, going all the way up to 2100+ rapid rating chess.com.
Hope this answers your question, and if you're interested in my other expertise as a coach, or have any further questions, please send me a message I would love to help!
Good luck in your chess journeys!

Essentially as title says. I am looking into maybe taking some lessons from a coach, but I dont want to change my opening setup much if at all (Reti as white and as black Caro, French and Nimzo). I was poking around, but cant find a way to find a coach who is familiar with the openings I know (as ~1800 blitz/rapid) to be able to have a bit of additional familiarity with my habits.
Is there a search thing I am missing, or is it just something I need to explore games of potential coaches for?
