Answer
The most common names for detective agencies are named for the owner, an individual, or a corporation. The reason an individual would use their own name is to promote their reputation for reliability and trustworthiness. Corporations, such as Pinkerton, have already built that reputation and can use it nationwide.
The next most common use regional names, such as Ohio Investigations, Reno Confidential Investigations, or Rocky Mountain Investigations; these names have a solid sound to them and people gravitate toward business using the local names.
Many agencies avoid using the word 'investigations' with names like James L. Rogers Services or Belmont Services, this can assist clients when writing checks or receiving phone messages that don't reveal the type of service that their using.
Movies and TV programs sometimes use cute names but in real life, cute is not practical. An agency with a name like 'Little Ladies Agency' or 'Hot Shot Investigations' doesn't really instill a lot of confidence; a client would be more likely to trust their private business and their money to a Paramount or Pinnacle Investigations.
A name that would be good for fiction could go with the 'Little Ladies' or the "Hot Shots', it would all depend on the type of story/script you're writing. You could choose from the name of lead character if that's the detective, something regional or solid from the setting of your story, or something that's fun or far out. It all depends on you and your story.
I like "Holmes Elementary Confidential Knowledge Services" (HECKS), Special Network for Observations, Operations, and Probes (SNOOP), or "Watson's Investigations Team" (WIT), but I've always liked a nice acronym.
Goon Detective Agency should be good enough.
