If you are a more experienced with 3D modeling on the computer, I would suggest trying out 3DS Max. It currently has a free 6 month license, you can find this here (http://www.students.autodesk.com) you can create a username for free and it also has many other programs for free. 3DS Max will also have tutorials available within the program (you can also find others on the internet) and if your model is well built, the renderings will look great! (If not, you can always touch them up in photoshop!) Hope this helps
