It's gonna be a long journey.....

Take your time and learn the basics first!

Model a cube!

texture that cube!

light that cube!

render that cube!

NEXT! good luck. I sugest you download the learning version of a few packges! They are free and all but the same as something costing $1,000's.

In all honesty a great modeler that cost next to nothing is Silo 3d from http://www.nevercenter.com/
