I can help you if you are still in need. I have made a few maps before, and all of them heavily command-based. I am wondering if the map is in 1.9 or 1.8 version. I can do all that you have asked for above, and more.

If you would like me on your team, please add me on Skype at mukmuk11144

Hello, I wish to apply but do not have Skype, and hope this will not affect this.

I am pretty good with redstone and commands but have not made a map before, how good a builder I am depends on your views.
I would like to help with the aspects requested for the map.

Please consider my application and reply.
If you need any more information just ask.
