How can ppc service help me to get recognize online?

In recent years, I've been in charge of a charitable organization in New Jersey dedicated to assisting children. While the NGO has gained popularity both online and offline, I desire more credibility and trustworthiness. As a result, many individuals have suggested that I hire a PPC marketing service provider and ensure its regular upkeep. However, I'm not very knowledgeable about technology and am unsure how to proceed. Can someone assist me with this?
