Anyone Know who Buys New Books Wholesale

So I got a new job, and have self published a book, but at this point just want to sell the 175 copies or so I have and move on-anyone can please help me to know of any sources that may buy my books? I paid $9 a copy for each one to print. I also can sell the copyright. I just need out at this point and to pay back the bank.
