Non-Target Senior seeking advice on Boutique Consulting Firms in NYC area

Hello WSO consulting community,

I am a senior at a Non-Target school on the east coast who will be graduating with an Econ degree in the spring. I've interned at a boutique wealth mgmt firm for the past two summers doing mostly research/analysis projects (finance/equity stuff). I'm looking to branch out into consulting because the quantitative/linear nature of finance didn't really do it for me. I've been reaching out to alumni who work in consulting for the past few months and have a few leads however I'm having trouble zeroing in on boutique consulting companies in the NYC (or Northeast) area. I'm focusing on boutique at the moment because I don't have a stellar GPA and know my chances at elite/big firms in Manhattan are slim (McKinsey/Deloitte/EY, etc.) Any advice on where to look for reputable consulting firms that aren't as big or competitive in nature to these large ones, where someone in my situation would be able to break in with the right tactics?

Your help is much appreciated
