[Ilaw] Seeking Top NYC/NYS Based High-Quality Plaintiff's Litigation/Collections Law Firm

Hi Listmates. Can someone please recommend a top NYC (preferably) or other NYS plaintiff’s-side litigation/collections law firm. We are looking for one that does high-quality work, is tenacious, and provides appropriate custom attention to cases (not a “mill”). Also, a firm that would do a few million dollars of collections cases on a contingency basis (preferably) or a hybrid with a reasonable modest retainer. Thank you! Much appreciated. Best regards, Evan
