There is a million free modeling programs out there. I don't know of anyone that does what you want to do cheaply. Z-Brush is by far the most powerful but it does have a steep learning curve for sure, Check the cool and groovy stuff links first then you may need only a simpilar modeling program that you can purchase. Like the free ones will fill a lot of gaps then a good all around modeler to do the rest. They're all rude and hard to learn in my opinion. E-On needs to make one Vue friendly Ha Ha... They got the simplify down to a art.
