Parts Help for 15 Motorized fader system

[Reubenclarke.jpg]

Hi,

I need help. I want to make a lighting midi controller. I need 15 motorized faders and 60 backlit buttons. 

I looked at many systems on how I could make this. I came across Midi Box and I like it so far. But I don't know what I'm doing. 

What Parts do I need to control 15 motorized faders and 60 buttons using this system and how would I connect it all. 

 

Thanks in advance
