2D SF style map-graphics for a 2D shooter-game

For a 2D SciFi style shooter game I need a collection of background maptiles and also some map-game-objects like machines. All is from the above-view (not 3D, not isometric), these tiles should be composed in 3d, structures/lighting created and then rendered to 2D-flat-tiles. I need floortiles, walls and some machine-like structures, three different styles with floortiles and different combination of walls. This is not for people who want just a fast job done but someone who also wants to learn (and get game credits). I want to create a mixture of the old 2D-pixeled graphic style/structures and modern 3D texturing. For this project I need good graphics with details and creativity. You will get next to payment credits in the game and of course a copy of the released game. Please read my recommandations to see that I am a good job-provider. I added a picture to show what kind of structures and texturing I need. I will provide a detailed document with exact definition of tiles and graphic styles. All map-tiles will have one size: 128x128 pixel, PNGs, 16bit, one transparent color. I need 3 different graphic styles*2 colorations. One maptile-style contains 4 floortiles*2variations, 4 edges*2 variations, 4 walls*2 variations = 12*2 tiles, at least 2 floortiles should be animated (20 frames). Many tiles of one style will be very alike so it is less work then it sounds, you will be able to copy many basic structures again and again. Please send a picture of Scifi-style game-graphics you already created, thanks. Christian
