To develop a texture and map it takes little time, however the complexity of you model would make a single texture a challenge. There is a texture plugin that will allow mapping in different forms, planes an arrangements, but it is not always perfect, and some tweaking of the mapping is always required.
There is no magic button or method to texture map.
If you model is made up of many objects, you can map each object to a texture, to achieve a better overall look.
