Help setting up interior design business

[David Marsceau]

Hey BP family ! This may be a shot in the dark because it's not directly about Investing but it does affect my future investing. My sister is an Interior Designer and has been working for someone else her whole career. She is now deciding to venture out on her own, and I am helping her start the business. Are there any other interior designers out there that have any advice as to the steps to starting the business as it pertains to licensing, and other legal aspects to be aware of ? She will be working out of her home office in Portland Oregon. Any help would be amazing , thanks !
