Thank you, you are exactly right. Working on CoffeeScript is my passion. I don't need any financial incentive to do it, I just need food, a place to live, and some cash to hold off my student loan creditors.
Kudos to you for having the stones to do this. I don't know much about CoffeeScript, but what you're doing is cool.
I think you might be selling yourself a bit low. The market value of someone at your level of skill is at least $8,000 per month, and I don't think you should be going down by 62.5% (as opposed to 20-30) just because it's a fun, open-source project. If it's genuinely commercially useful, you should be shooting for market salary.
I would set the same price but make the promise 2 months, if it were me.
