ISO "sushi grade" fish in Philly/South Jersey

Before I start I'd like to state I know the term "sushi grade" is a bit of a marketing ploy. Me and my partner had an idea to make sushi so we ordered all the things to make it and were pretty excited to do so...until we realized it's literally less expensive for us to both go out to a sushi place and eat than it is for a pound of "sushi" fish at Wegmans.

Does anyone have any recommendations for sushi quality fish in Philly or South Jersey? Preferably ones you've gone to before and have lived to be on Reddit right now haha.

Thanks! :D
