Computer Room Design

Is there any software that is absolutely free, with no obligations or watermarks, etc. out there for creating and printing my own business cards? I want to download a program that will let me put my own picture and my own writing on it, then print at home? I keep downloading software that says absolutely free then after I go through the process of designing my card I get a message saying that my free-trial offer only allows me to print up with a watermark. I have to purchase to get one without watermark.

I’m looking for CAD (computer-assisted design) software to do 2D and 3D design, drafting and modeling for interior design/decoration. The software should be free or not very expensive for non-professionals. It should be able to create 2D floor plans and object sections and outlines as well as 3D models or objects, rooms and houses, with colors, textures, and lighting effects.

I am looking to design my own backyard landscaping and am looking for software. Either free or worth the price. I want something that I can enter a pic or create a sketch of my own home and landscape around it. Thank you.

I need a software (a free one) to decorate my room.

Does anyone know any software, free and commercial, which I can use to design rooms, landscape and other for my 3d movie?
If anyone is using iclone 3 pro, does it come with such an option?
Thanks!
