I turn nouns into concepts while drinking excessive amounts of coffee.
I definitely agree I have received bad advice.
However, let me clarify.
It wasn't the LLC decision that led me to negative networking, the choice of "branding" with a "production company name" is what became negative networking.
For example, it is pretty common among students in film school to form small partnerships with other students and tend to do many projects together. It is also common for that to spur into a "production company name" that they start attaching to all of the projects they do together as a team. I myself chose to go that route twice with others and execute projects as a team under a branded name which developed more negativity than positive exposure.
The other production companies and teams in the area overlooked all of us when searching for crew hire because they assumed we all only worked together and under that brand name.
If I was to give any counsel to students on the verge of graduating film school or even those out there planning on making a few films, it would be not to brand yourself with a production company name rather than just using your name.
