I hope you’ve already come to terms that you will probably see no return on the time you invested in the past two years, and that you are not simply still in the denial phase trying to squeeze something out of your efforts.
If you sell your code, the most it would probably fetch is somewhere in the low three digits, and it would probably be snapped up by someone who doesn’t care about the business they just want to have a beefy open source project as part of their resume or portfolio (which is basically the smart way to get open source credibility without toiling for years to no end, think about it, 300 bucks buys two years of open source experience).
If I were you, I’d beat them to the punch and open source your project and move on with your life, let others maintain it and maybe make it into something great.
