Wikipedia is quite a smart platform. It knows everything about people, business and about itself as well. Whatever you want to know about the page creation, you will find it right there in its own page creation guidelines. This is why anyone can write a wikipedia page. However, you can easily find any affordable ghostwriting services and ask them to write for you or for your wiki. If anyone is able to write for wikipedia then all I can say is that hiring a professional would be the best thing to do. Moreover, ghostwriters can do that too. Do you agree?
