That is a good amount of traffic. I hope you are monetizing it somehow. My best advice is to get yourself a broker or someone that is experienced with selling a website. I tried selling one of my websites for months with nothing but shitty offers on sites like sitepoint, and website broker. Then I found an experienced broker, and I ended up making almost $60K more. My biggest issue was I didn't know what my site was really worth. Don't settle for less than what it is worth. There is plenty of people out there that will pay the full value of your website or close to it.
