Francisco de Quevedo: need a Miniature.

I am doing an En Garde War Band based on the Captain Alatriste novels. I would love to find a figure that could represent his friend Francisco de Quevedo

He's a fairly distinctive looking fellow shown here in a contemporary portrait and as he was realized in the Movie Alatriste 

He's another image from the same film.  I feel the eye glasses and beard/mustache are the key elements.

Any one have any suggestion
