Best Places To Buy Freshwater Shrimp for Aquarium

I’m starting up a small 5-gallon freshwater shrimp tank and I’m looking for recommendations for places to buy shrimp once the tank is ready!
Does anyone have any reputable websites that ship freshwater shrimp, especially places with cool/unusual colors or varieties?

I live in NJ so I’d love recommendations for any aquarium/fish stores in NJ (or nearby) that usually have a good shrimp selection beyond the basic ghost/cherry shrimp you see at Petco/PetSmart.

I’m pretty new to keeping shrimp, so I’d love recommendations from people who have had a good experience with healthy shrimp!
