Creating a name for a brand and company that is professional yet catchy. : Business

I want to created a video game about mercenaries like army of two I also want to open a company to hold the intellectual property of the video game brand and related projects I want to promote.

I have a few names in mind but I am not sure if it is professional enough to use.

The names I have are bastard brigade/squad/league, legion(s) of rust ,can't hang twice and asshole brigade/squad/league.

Names I have for the ip holding company is C.H.T. , Moonlighters or 13boards Studios.

To put it out there, I have dabbled with creating llcs in my state and some knowledge of how taxes work. However I have no real world experience in marketing advertising running a business fund raising programming or anything else for that matter.

Are these names good for the brand and company I want to promote? What would be a realistic time frame for something like this and cost? Do I need to hire outside help or could I do sweat equity and do it solo? What other industries could be used to generate income to help create games and other projects related to the brand? What advise and considerations would help make this a reality?
