I think you should do your own framing, but frame the pieces VERY nicely. Also, paint to standard sizes so you can use your frames again if need be. Check out
www.jfmenterprises.net but be aware that the shipping may cost you as much as the frames themselves.
On the brochure I have two suggestions: Far fewer words. More images. Hardly anyone will read all that stuff.
You need lots of large images that show full portraits, not cropped in tightly as you've shown. Also I'd get rid of the green shapes. They don't add anything, in my opinion.
Also, I don't think that Unconventional describes your portraits at all. That word is better suited to Odd Nerdrum or Lucian Freud.
