Graphic Design for Mobile App Game

Hello, We are developing a mobile game with horizontal scrolling. To us is urgent to have all the graphical aspects; we are looking for a serious, full time, and dedicated work, where a good communication is the key. Graphic wise what we need is 18 complex background, plus 8 backgrounds for what will be considered underground in the game. We need 58 obstacles (some may be animated), 81 standalone objects, 74 decorative objects, and 8 underground passages (meaning images in which the character will walk in and appear inside the underground). Lastly, we need 29 terrains, which will have to be tileable, and other 9 platforms (such as floating islands) that will have to be tileable as well (so by tileable I mean that these will have to be able to be stretched and moved by the developers). Again, we are looking for a serious, fast, and effective work, and for someone to have a good experience.
