Hiring a PR firm can help you to come up with a systematic plan to stay in the public eye. It is a great way to popularize your achievements and goals and establish yourself as a revered public figure. Your PR agency will release your pictures, videos, news and quotes to journalists and thus create a buzz around you. It will increase your chances to get hired and your work to get more viewers.
A PR firm works in sync with your marketing team and gets information about your events, tours and other marketing efforts published.
There are no disadvantages of hiring a PR firm other than you may get busy with popularity and work, and that you may have to turn down a few offers due to the lack of free time on your schedule.
