Honestly, from one developer to another. You are goin g to be pretty hardpressed to find a project you will be interested in and get paid when it comes to the minecraft community.
You could go into making mods and doing the donation thing, but when it comes to servers it ~90% all volunteer work. You just need to enjoy the community you work for and have other things on the side to make money. That's just the way servers are.
On the other hand though, if you want be a part of a server that can possibly pay you; servers like herocraft and buxville would have their own application system for developers and not google or search planet minecraft to find devlopers.
If you want to develop and not expect money in return I am the admin of the development team on Gildorym. Feel free to apply there if you want.
