In the past, wedding consultants were for the wealthy. That has changed over the years, and now there are wedding consultant services for every budget. Consultants typically charge differently depending on what services are provided. Consultations, day-of, and freelance services can either be billed by the hour or by a flat fee, depending what is involved. Start-to-Finish services are typically billed as a percentage of the overall wedding budget. Anywhere from 10% to 20% is normal, depending on where you live and the expertise and experience of the consultant.
