I'm trying to put some objects inside a 3D bottle, anyone?

I am designing a logo for a company I'm opening and am trying to put some text, sand, water, etc inside of a 3D bottle. I found this tutorial (http://vector.tutsplus.com/tutorials/designing/working-with-3d-objects -and-transparencies-to-make-a-vector-cola-bottle-design/) but it mirrors everything when you do the 3d rotate on the bottle, where I'm wanting sand and water only in half of the bottle and text, mountains, etc. on the other half. What would be the easiest way to do this? I've been googling around for a week now and haven't found a tutorial that helps more than the coke bottle. Basically I don't want to mirror everything that's in one side of the bottle. I'll attach a sketch of what I'm trying to accomplish. The sooner the better, and any help would be greatly appreciated. I'm trying to design it tonight.
