Hello Iplay_gamer, and welcome to the forums!

You should check out the Wiki as well as the Tutorials subsection of the forum. Your best bet may well be to take a look at Duna missions currently around on the forums for ideas of how much craft you'll need to do the job. It's really just a bit more than what you need to do a mission to the Mun and back.

Happy landings!

Need to get to Duna. Ok.

Can't refuel. Ok.

Manned mission. Ok

May I ask why you need to get back to Kerbin so quickly? Is it for a challenge or something?

Anyway, I would suggest following Starhawk's suggestions. I can make some of my own, but I need to know more info.
