I don't know, but in case of a project such as this one, how do you imagine other people' contribution to the project exactly ? Since these roles are not paid obviously and "a couple of hours weekly" is not, in your words, justified for a developer role, then how do you really expect that this project will move on? Guys skilled enough to fix things and with the ability to literally donate their time to this cause, will most definitelly not do it for tens of hours every week for free just because you expect them to do so. I would even dare to say, that you are not left with many options besides this one, because as @shroomion said - people usually have to deliver results in order to cover their own bills. So, unless you offer an honest job to anyone willing to spend a ton of time OR get anyone left with a couple of hours of free time every week working for free basically, I'm really not sure what your plan is honestly. I think that you especially should be the first one to call this out - and don't get me wrong, this is not supposed to be any kind of rant, but just objective view of things.
