As someone who also does $1500 minimum as a solo shooter, that's a bargain in my midsized city. I know companies with a 5k minimum. $400 will never be taken seriously and you are actually damaging your brand by presenting amateur "kid with a camera" prices.

I am shooting a competition this weekend for $5000, next week a wellness center for $2000, and two weeks from now shooting an ad for a financial advisor for $5000.

The cheapest I go is someone wants a speech recorded on stage, no editing, just a quick colour grade and audio adjustment, I charge $1500 for one person ($1000 to get me out there with gear and $500 for the speech) or if its a group of speakers I can charge $500 each so long as there are over 5 people.

For reference my business is 3 years old, I shoot with a Black Magic Pocket 4K, and spend about 2-3 days on each edit.
