Why do you think most independent CG films are barely 10-15 mins long. Even films from places like pixar, which do have access to 2000 node render farms.

My suggestions:

1. Get a better render engine then poser. It will save you time and money in the long run. Poser's renderers, both firefly and the old one, are absolutely the slowest renderers of any 3D app out there. Even free ones like pixie, 3delight, yafray and povray beat the pants off em, much less the high end ones. No point in throwing hardware at poser.

2. Aim for a realistic movie size, say 2-3 mins for your first work. That is more then enough to tell an interesting story. Typical TV ads tell a whole story in 20-30 secs, no reason you cant do the same in 6 times that. You can get as ambitious as you want for your later projects after you have a better understanding of the process.

3. Make storyboards and lists of everything before you even touch a computer, and more important stick with them once you do start. If you don't you will be stuck revising stuff again and again.
