How many pages?

I think a 5.5 X 8.5 inch booklet. With perhaps 2-3 items on each page. I will be updating my project shortly with more info. But, the feel I'm looking for is like the World Vision catalogs. Here's an example: https://www.google.ca/search?q=christmas+catalogues+template+for+charities&rlz=1C1CHFX_enCA530CA530&source=lnms&tbm=isch&sa=X&ei=yyU7UpHRLcGriQLXk4G4Cw&ved=0CAkQ_AUoAQ&biw=1304&bih=664&dpr=1#facrc=_&imgdii=mu7KkbJy7YoOhM%3A%3ByaIPaFO7gXgVCM%3Bmu7KkbJy7YoOhM%3A&imgrc=mu7KkbJy7YoOhM%3A%3BzKBy-G7WW6iKJM%3Bhttp%253A%252F%252F4

Thank you!
