Local Sellers/Consignment options? Long Island, NY

Hi! I have a bunch of nice clothes that I would love to sell. I don’t mind splitting profits! I’ve seen mixed reviews about selling through the Poshmark consignment program (people keeping your items without even trying to sell), or ThredUp. I don’t know much about flyp or how it works. I’d love to hire someone or connect with a trustworthy business that would sell my items (or at least try to). For reference, I have MANY pairs of Madewell jeans, Everlane pants, and several other tops/dresses (brands like Abercrombie, French Connection), etc. Thank you in advance for any help or advice with this!
