​Easiest way to get an LLC?

Looking for the simplest, and I guess, cheapest way to get an LLC registered in my name. I’ve not finalized the state yet but I’ll choose from either Texas, Florida, or Nevada. That apart, I’m just asking for the easiest way I can get an LLC?

For those who have registered their LLCs on their own, would you recommend DIY or paying an LLC service to do it for you. I’ve heard I need to get a registered agent any way so it’s better to pay a bit more upfront and let them handle all of it.
