everyone expectation of earning is different,
cost of living is different,
spending habit is also different,
the set up of business is different,
skills also different
workflow also different
deliverable products is also different,
so each photographer have to find out what are their own expenses, expecting earning and work out their own rate, you can't simply cut and paste other people price list to use as your own, it may not suit you.
Here is a calculator you can use to find out how much is your day rate,

work out your own cost is a process, you need to fine tune it as you go along, reviewing them on a regular basis, like 6 months or yearly to keep up with the present economy situation.
as for the outcome for that event?
I guess nobody will bother,
when people have a mindset of photography don't worth any money, they won't change,
if can get it for cheap and free, than will go for it.
if can't not find, then just forget it, they don't really need it anyway.
the change only take place when people start to have emotion connection with the photos, which can not be measure by money,
"how many hours of coverage", "how many photos", "how big is the photos" are just secondary.
