Need Pixel Art for Web-Based Game

This will be an on-going project for the text-based MMORPG known as Gates of Survival ([login to view URL]). We need a pixel artist to make new art and images for the game, and we definitely need someone who is willing to work with us on more than just this one project (we're going to have many in the future). Right now, we have Pets in our game; however, we need to add a bunch more. We're looking for a simple style similar to the Pets attached to this project. We're willing to do either by the hour for the art, or by image. We're likely going to need maybe around 5 - 10 Pets made for right now, but as I said, more in the future as well. We also have openings for a ton of other pixel art in the game outside of just the Pets, which we can talk about once we have a completed project here. Thanks.
