Questions about portfolio (sales)

I posted this on Apug earlier. I thought that perhaps some of you here would have experience from which to respond to these questions of mine, if you wish.

From the outset of my journey to Italy, I had considered offering a portfolio of those images for sale. My thoughts immediately considered doing this in Pt-pd. These will entail enlarged negatives and my questions are these...

1. What image size should I consider? I have been thinking of 8X10 mounted and overmatted to 13X16. Is that a good size or should I consider larger or smaller?

2. Is Pt-pd the proper print medium? Does it have the inherent characteristics of being more collectible?

3. How many images should the portfolio contain? I have been thinking in terms of 8, 10 or 12 images. Is one of these a better number?

4. Who makes custome portfolio cases? I am thinking in fine linen covered cases. Is that the best way to go?

5. If you were to produce something like this, what price would you consider placing on the portfolio?

6. What edition size would you consider appropriate? I am thinking in terms of ten or twelve portfolios...is my thinking correct on this?

Thanks in advance to all who share their thoughts and experience on this matter

I print to an 11x17 sheet of watercolor quality paper, then cut to an 11x11 size. I had a book binder make an Italian fabric covered clamshell case for the portfolio. This was cheaper than going to a portfolio company. I have 10 copies.

Thanks Walt, Nice work and good information. Much appreciated.
