Here's my $0.02:

You don't need to be good at "monetizing" to just ask people how you can improve. Throw a little survey box in the corner, and the people that use this thing enough will let you know what would make their lives better. Those people will use that thing, and you ask them to contribute ($$$) a little bit so that you can do more of that. Some of them will do it.

congrats on building something useful, most companies struggle to do that, looks like you're about to kill it!
