I’m fortunate to not have to deal with billing but I’ve worked with local animators/motion graphics artists on the recieving end of HD projects.
Since the files sizes will be 6 Mb per frame instead or 1 Mb, consider the amount of time it will take to render your projects. It isn’t linear – more likely about 3 times longer.
The output can be tif or targa sequences or Quicktime movies. That too will take a bit longer but delivering files is much more convenient than videotape. If you factor that into your project quote you should be in the ballpark.
Hopefully other COW sages may wish add to this post to give you an enlightened answer. Good luck.
