Fix n Flip Design Team

I am considering bringing on someone to my team that specializes in residential design or shall I say, redesign.  Someone that knows the newest trends for interior design.  Not furnishings but selecting the materials that will go into the new design of the home.  Is that a thing?  If so, who would I search for?  I've called some interior designs companies and they sound like I've invented fire or something.  Thank!
