Graphic variations of Floor-Map-Tiles of a 2D-SciFi-Game

For a 2D shooter game I need graphic variations of already painted FloorTiles (128*128 pixel). I think you need to have experience in pixeling / SciFi texturing. The results must look good enought to be used in a PC/console game. If you are serious about this task please send an example as described in DOC, thank you. I also like to see additional gfx works of you. The task: There are already 3 different styles in 2 colorations, each has 4 MapTiles. The current maptiles are creative in texturing, but still need variations in color and structure. I need: (a) from the same style created different structured versions (changing some part of the texture/structures with pixelstyle-compositing) -> 4 Tiles varied in every style meaning 12 new structure/texture-varied MapTiles. (b) every MapTile in new colors which will match the other colors of that style and the walltile. -> Every existing MapTile-Style should get one new coloration: sum is 3*4 floortiles changed in color [easy and fast task]. (c) we need some of the floor-structures colored (with a second shade of color) in a way that there is more complexity and not just one color. -> 3 MapTiles in every Style need a new structure, choose some of the original, some of your new created ones: the sum is 9 new FloorTiles with new second-added-color-with-structure. (d) adding some simple animations, mostly a blinking/fading light and rotating lights. -> 2 Maptiles of every style [choose some of the original, some of your new created ones] should have animations, so 6 animated Maptiles with 28-40 animation-steps (smooth movement or color changes). (e) adding some transparent fields -> 2 Maptiles of every style [choose some of the original, some of your new created ones] should have transparent structures, so 6 additional Maptiles with new transparent structures [easy and fast task].
