Wikipedia is itself a volunteer-based platform for everyone. It does not charge a single penny from businesses. Although, there are many external third-party outsourcing agencies that create professional Wikipedia page for Company USA. These agencies can charge fees for their services to clients. Their charges may range from 250 dollars to 3000 dollars. It may even go higher and depends on the affordability of clients. Companies are willing to spend millions of dollars for publishing and showing their articles on Wikipedia. But Wikipedia works on strict rules and regulations. It follows its stringent guidelines and takes enough time to approve your Wikipedia page article.
many wikipedia experts taking too much for page creation, but I took services from wikicyclopedia.com/ their pricing of the services is so reasonable and they deliver work on time.
