Hi there.
I would like to express my interest in this kind of work, although it's a bit vague at the moment and I'll have a few questions about what will be required.
I am a freelance animator with good experience in animation and 3D modeling. I have some experience in creating content for games as well: I have created animations and a rig for use within the Unity Game Engine, have had experience in a number of personal game objects, and an item of my work was released in Team Fortress 2 a few years ago. Check out my showreel to see the quality of my work
I am also a trained illustrator with knowledge of colour theory and style. I'd be interested in doing the backgrounds as well. I have a good base knowledge of computer games and what requirements are generally needed of the artists.
For all that, I do have a few questions however. Your title and description don't match what you're after: both character creation and animating/rigging, or just one? Also, what is the scope of what you would like the animator to do (as in, rig 5 character, have 2 unique walk cycles, etc)? It might be a good idea to update your original listing with a more detailed account of what you want and needs to be done.
Thank you for your consideration,
Julien Le Cocq
