Hypothetical question

EDIT: added more context below. Setting up an LLC in Florida. Every formation service wants to upsell me on registered agent service for $99-199/year. Can I just be my own registered agent? I work from home.

Illustrative response

thanks all. gonna start as my own since I'm home all day anyway, see how it goes. if i get tired of the spam mail I'll switch to a service
