Legos pleeeeease (South San Antonio)

Huge ask: so I kinda have pondered the idea and I think I kinda Wana start a club or something at school. and was wondering if any of y'all has any Legos, bulks of Legos, etc that you'd be willing to part with?? Thank you in advance for any and all help with this. I'm also also asking if any of y'all lil kids that have the larger type of Legos like the Duplo and megablocks ones. The more the merrier, it's cuz I Wana use those for my classroom to build useful things in my classroom such as trays/shelves sore kids to turn in things, containers/bins to put things such as pencils and other supplies. Just make it a lil different. If u do, I'd be so eternally grateful. I'm in the 78221 zip near southpark but can travel. Thank you so so much in advance.
