Looking for free manure for school gardens/compost project

Good day! I hope you are well. I’m looking to get some manure pretty regularly for my school gardens in East Providence RI. If anyone in East Providence or surrounding towns has excess manure especially ( rabbit, goat, llama, alpaca) I would love to come by with a shovel/fork and fill my truck or buckets with whatever excess you can spare. All herbivore manure is welcome.

Thanks for taking the time to read.
