blender mesh rig and deform

The worker will receive a .blend file, containing a male mesh. It is ready to rig, with vertex groups. The worker will receive also 4 pictures of postural misalignments in humans. The job is to rig the mesh, reproduce with it each postural type and save the deformed mesh to a different file. Worker will have to provide thus 4 output .blend files. Each one will have same rigged mesh but deformed in a different way. In the .blend file with male mesh, there is also a little plane which need not be touched: it is to be kept in each output file. base male mesh file is slightly bigger than 25MB so i will send it upon project approval. Here i attach the posture images and a couple of screenshots of the base male mesh. Thanks
