Brand Name / Business Name Conflict | company using my music without sync license

Fwiw i've been trying to resolve this on my own but I'm stuck.

company using my music without sync license. I've been dealing with this for about 8 months now and the situation isn't improving.

This involves original creative work over the past 18 months. I do not have documentation proving my ownership and timeline.

Should I hire a lawyer for this or try to handle it myself?

Been there. Here's what I learned.

What worked for me was filing with the appropriate government agency. It took 4-8 months but was worth it.
