Look beyond law firms!
Look up Litigation Support Services. They help law firms get the documents in a case, and sometimes help put together videos like "a day in the life of Joe Smith." Such as when trying to show how difficult life has been for Joe since the traffic accident. I see Magnolia Legal Support, Trial Concepts, Quality Litigation Support (they look like a smaller company, and might appreciate the help), Persuasion LLC, to name a few. Familiarize yourself with this type of service before reaching out to them. While big law firms can contract out, smaller firms do most of this themselves!
Scroll to the bottom of the page on this link. They are looking for someone! (I would guess there would be strong competition, but, it is worth a try! https://www.nlg-npap.org/our-programs/
A little bit about them. NPAP is the National Police Accountability Project. It is a group of lawyers sharing information to help each other in cases involving police officers violating prisoners civil rights. It is headquartered in NOLA. It is an awesome group of people.
