[LAU] How can we convert money to fixing bugs in software?

Hi, I was wondering, what can we non-dev users do when our favorite piece of FOSS software is lacking a little feature, but one that makes the software for us of little or no use? I'm thinking of seq24 not working, since a year or so, with JACK Transport - which for an app like seq24 makes it almost useless. It really itches me and I'd like to do what's in my power to help fix it. I was thinking, since this would be (I think) a few hours of devs work, couldn't I/we raise some money to pay a dev to do it? How would I/we do it? In long term thinking, we could have a site where users propose a bug, devs name a price for it, and when the money raising reaches that quantity, the dev starts to work on it and when he fixes it he recieves the money. Basically a mix of kickstarter and amazon's mechanical turk. I think this could work quite well for such bugs, which often appear in awesome but semi-abandoned software (freewheeling and kluppe for example come to [my] mind). I totally get that the original devs may have lost interest and moved on in life, but being FOSS, the code is there and maybe a few paid hours of a dev could get it working/add a basic feature you really need.
