Website Summary
Age range
Older generations that have either digital scans of old photos, or have old photos and live in the St. George area.
Gender
It's more typical for old women to hang onto (or own/keep track of) old photos or to have them digitized, so it's likely more of the site's user base will be female than male.
Geo-location
Anyone that can email high-quality photos can use the service, though I can personally make visits in the St. George for scanning services. St. George for the most part, but availible to anyone online.
Other factors
Again with the older generations, the target audience may not be too technically inclined. This means the site needs to be as easy to use as possible, even on mobile devices. Information also needs to be clearly stated and easy to read, in case of vision problems. It's not uncommon for older users to turn the font size way up on their devices as well, so having a larger-than-average font size around all of the site might also be a goo idea.
