Isometric Game Avatar design

We have a set of approximately 6 avatars - south facing only, for use within an isometric game. We are looking for somebody to design our avatars in all positions, ie. - north, east, nw, se, etc. - walking - sitting, etc Please see [login to view URL] for a clearer example. We require smooth movement - as 'realistic' as possible - you should be able to demonstrate the finished product to us. This is the early stages of our project and we look forward to building a long term working relationsip.
