What do i need to accomplish my goal of 3d model?

Hi to all and thanks for reading my post.

I would like to create a 3d model, for a game that i would like it create and i am trying to create a model for it. I was wonder what would be a good FREE program to do this since aim out of work and have no start up money for this. I have always wanted to be a game programmer ever since i played my first arcade game and my Commander PC. This has been in my mind for years, which i have been make notes on what type of game that would be an additive game that people would enjoy to play and would come back and play again.

I own an Xbox 360 and have found that the Xbox live arcade games as well as Internet mini games as i call them like Heavy Weapons, Hexic, and Gemoetry Wars Evolved. Programming is not new to me. I have had the usual course that most people take C++ and Visual basic. Unfortunately as far as the graphics goes i have had little to no experience with them. So which bring me here to my other fellow programmers that are also looking for a like help.

So any one who can help with some info on a free application that is easy but has a full range of options that is as good as the full $5000 dollar software package.

Thanks for listening....god be with you all.
