with the out of date old amiga bounty system, things either take years or never get done.
put up a kickstarter have it run for four weeks ask for the money you need... when you got the money, finish the project to the set deadline in the kickstarter...
if you don't get the money for the kickstarter you need, then you know there is not enough interest in this project, and its not meant to be.
