Josh, I have hundreds, maybe even thousands of large (1-1.5cm) live shrimp. You are welcome to all you can catch for free anytime. You might just wana bring a 5gal bucket or two and toss the chaeto and rubble into it and take it with you or something to seed your tank from it. I wouldn't be able to tell you the species, but they reproduce fast, and grow larger than any brine shrimp that I've seen.
