There is a risk of not finding a suitable person for the job we need. On some occasions we hire a person who may never have had experience in the sector in which our company operates, which may cause misunderstandings or may not capture the essence of what we want.
Generally, the freelancer has more clients, which will not be available 100% of the time, and may take longer to deliver the work.
Everything you delegate to the freelancer will have an impact on the company's image, since they will be in charge of the visual part.
