I made use of Google's free modelling program Google Sketchup. Sketchup doesn't have a render program built within but you can export it to another program called Kerkythea for rendering. A little warning though; Kerkythea is not really for newbies, but it's free so it's worth learning. There are many tutorials to be found online and on youtube.
Each one took about 5-10 hours modelling time and up to 1 day rendering time.
