Some very elementary and subjective math:
Numbers taken from averages on Movie theater marketing services web sites.
Production cost for 30 second video: $1500
Cost to run ad in a multi plex for one month: $1500
So, if you do 30 jobs a year you have added a $100 per event expense to each job, and you have only received 1 month of advertising.
Now, papa, you have a fair sample of what your market will pay. Apparently 225 per event is too high. So, make it 200 per.
$200 - $100 = $100.
Lets assume you have fabulously inexpensive insurance, minimal fixed and variable (travel, supply, uniform, maintenance, etc) costs and no depreciation costs. $30 seems like a small enough figure to use.
$100 - 30 = $70
So the use of your equipment, any necessary travel, and strike and performance time is only worth $35/hr?
I bet there are other expenses I have not even included or considered that would render that number optimistic.
I would not be able to justify that advertising expense.
Even if you did 50 jobs annually @ $200. The subject expense would still be about 30% of revenue before any other expenses are calculated. Still to high in my book.
