3D Mock PSD file of men's legs - for a men's leggings business to showcase it's leggings designs

We sell men's leggings, and currently shoot all of our products on live models. We would like to now use 3D photoshop models to showcase our designs. So...we are after someone that can produce a 3D mockup of male legs that we can skin with our different leggings designs. Our designer is currently using a 3D female mockup to test our new designs, you can see how these look on the attached document ''CURRENT 3D WOMEN'S LEGS'' The "right" legs are clean, sharp, can be viewed from multiple angles, and can clearly be identified as male. If we can find or create a 'male' version of the current female legs we are using that allows for output like the shots pictured below, that would be ideal. We're not clear on the method used to create this mockup, but think it's made in Photoshop Extended (which has it's own 3D application) and is likely called a"Ghosted Mockup". BUT, we're not sure, so any advice / direction appreciated. To help show the process needed to achieve what we're after, our designer has created a video showing how he skins our designs on the female mockup in Photoshop: [login to view URL]> Ultimately the output of this job is the mock PSD that our designer starts with...remember the procedure in the video snippet? Open the mock, click on the "special layer" -a new window opens up, put the design on that and then the first window shows it wrapped." - so it's a .PSD file we're after. I think that covers everything, let me know if you have any questions or need any more information to do the task!? Thanks!
