Public Relations (PR) agencies typically charge anywhere from $2000 to $25,000 a month for their services. That being said, small business owners can expect to pay PR firms $2000 to $10,000 for various services (this depends on the services you need, their experience, and the location of your business and the PR firm. Some project-based works such as writing a press release can cost between $200-2000; however, it is more common for PR firms to charge via retainers and additional fees for extra time (or projects outside of the scope), but the amount of projects and potential prices a PR agency can offer is vast.
