Blender Animation

Hi I'm looking for someone who's experienced in Blender to create a simple animation that's less than half a minute (shouldn't take that much of an effort). I already have the model rigged and the scene set, so probably, only animation would be needed although if improvements can be made to the existing rigging and all, by all means. There are more specific requirements but I'll discuss further details with interested parties. A little troubleshooting may be involved too. Rendering of the current .blend file causes Blender to crash although the cause is still not known. Budget wise, since the basis is already provided, and only animation is needed, the budget is unfortunately not high (<= $70). This is negotiable though, if I can be convinced. Anyone who's interested, let me know. Also committed, interested applicants please.
