CGtuts+, the new CG tutorials site opened today by the Envato Network, if offering their first Blender tutorial on Low-Poly modeling and the creation of normal maps. If you're interested in writing for them: they pay $150 for tutorials. Maybe that's a nice way to make some more money with Blender for you?

Normal maps are widely used in games to make low poly models look high poly. In this tutorial you will learn how to create a high res Skull model, generate a normal map from that model and learn how to apply this to its low poly version.
Techniques covered in this tutorial include multires sculpting, baking a normal map, baking ambient occlusion and applying the maps to a low poly model.
This tutorial uses the free and open source Blender suite. If you're new to 3D, following this tutorial in Blender is an excellent way for beginners to get started. (Don't worry - this tutorial has plenty of techniques for more advanced users too!)
