What are the advantages of having Wikipedia?

A number of young adults recently started NGOs that are still in business. They are aware of the Wikipedia page but have never updated it, so they really need to know who provides the best nearby Wikipedia page creation services. They are aware that they can write your story for Wikipedia and create a page for you because doing so will assist them in establishing the online presence of their non-profit and earning the trust of audiences. Would you please suggest the best services for creating Wikipedia pages?
