Here from the Secretary of state: The state of Oregon doesn't have a general business license. However, many occupations and business activities require special licenses, permits or certifications from state agencies or boards.  Further, there is a directory that you can search to see if your busness requires a license, which I am going to give you here.  But if you put in "floral" or "wedding" it does not appear you need a license to create the deigns and arrangements for weddings.  Your contract will govern. The Terms of Service needs to be reviewed to make sure it will hold up as one.  Good luck.https://apps.oregon.gov/sos/licensedirectory
