Thank you for your information.  He did say he was more familiar with Poser, not Daz Studio.  And suggested I get together with my friend who knows how to "manually" install a Poser product to DS.  This vendor, and another one, who designed some Native American clothing, etc., for M3,V3, and Mil Horse, did say their products would work in the Daz Studio.  They may just need to be "manually" installed. 
I am very new to all of this so if you or someone has some pointers on how to "manually" install the Poser products to DS, I would appreciate your help.
Thanks again for your response.
