Hello, first time posting in this community. I am a licensed mechanical engineer with a total of 5 years of experience in MEP. I am looking for some side work outside after I quit my current MEP job (got a new job in a different industry). I am aware that I need to get E&O insurance, form an LLC and get a CAD software, but are there anything else I need to watch out for? A friend of mine has asked if I can do design work for a custom 8000 SF house. I want to make sure I have all of my basis covered and would like to get some insight from the community. Thank you!
