You should avoid the contract approach. We advise you to never hire a service provider who binds your contract. When you find a company that is ready to deliver the most promising results, you don't have to worry about contracted service providers.
All you have to do is focus on a PR agency that can work 24/7. A large number of PR agencies usually show up outside of normal business hours as well as on weekends. You can get the best information about public relations agency via https://www.believeadvertising.com/services/public-relations/.
