ISO long 25.4 standard 4 bolt seatpost

Hello all. Like the title says. I’m looking for 500mm, hopefully longer. 25.4 diameter, standard 4 bolt. I’m in Oak park, Illinois, USA. I can pay shipping of course (if you are in the lower 48) Show me what you have and how much you want. UDC has a Club steel post that I can get for about $40 including shipping so wouldn’t make much sense for me to spend more than that. Just hoping to put a post to use that is otherwise laying around. Thanks everyone!
