So you want a string of LEDs that can change between 1000 and 6000 LEDs and you want to be able to control any one of them.
While theoretically this is possible in practice it is a huge and very expensive project if you are to get it right.
I think it is beyond your capabilities.
Have you seen what the LEDs alone would cost, then you need to chain controllers together, and maybe make different networks banks of these controllers.

I would suggest looking into some of the color change LED christmas light hacks out there. The following link has a pretty good explaination of how they work. You might be able to adapt something from this to your needs.
