Some worries I have run into are meeting the page limit. I have only 6 photos at the moment which is about three sets(each photo is group together). This was due to not having a heck-ton of film, and I couldn't order anymore at this time. Like I said I still need to put the photos in an order, so that it would make sense and I can meet the requirements. This is really my only struggle. I just hope it's enough to make people understand what I'm going for.
In my original plan, I wanted to get some testimonials as well. I still need to do that too. That won't be as vigorous, but I thought I'd mention it.
Good luck on your essays.
