Vested Wellness Entrepreneur

I have questions on what I need to do as a LLC since I do want to combine an herbal product business with a consult business. I need to know what is required of me legally and tax wise. I have tried to do some research but its not my strong suit.

I started out in 2008 wanting to invest our then stimulus checks into something that I can grow into a full time career. I supported a hobby herb making business to this day. I started a food trailer to learn the ways of a commercial kitchen because some of the new herbal products I wanted to make required me to do so. I did that for a year. I would have kept going but my commissary kitchen was closed without notice. (local legion) I have not been very active in the last three years cause I got married and had a baby that ended up with liver cancer. Anyway when he was born I enrolled in the last phase of what I wanted this business to be a full supplier of herbal products integrated with health coaching and a safe place for people to go to find alternatives to their everyday lives. I currently run the business out of a vintage trailer at my home. I have not started to see clients yet due to my son being sick and covid. I'm eager to blend the businesses together into a LLC.
