Hello! I might be the man for the job.
(Just a note: I charge between $120 and $200 for a Wikipedia article. If we reach an agreement, you can close this competition and hire me for less.)
I'm a former Wikipedia administrator. As a freelance writer, I have published more than a hundred Wiki pages for different people and companies.
I will create a well-formatted page that is fully supported by online references. Before publishing, I will send you the draft so you can provide comments and proposals. Once we have agreed on the final article, I can publish it immediately.
Please tell me the subject in advance. I only accept a job if I believe it has a chance on Wikipedia.
Once I publish your page, we wait for 7 days. If the page has not been nominated for deletion in that time, you pay my fee. Otherwise you don't owe me anything.
My fee depends on the size of the Wikipedia article. If there is enough material for a short article, it costs $120. I charge $160 for an average-sized article. When there are many sources and the article is complex, I charge $200. I will tell you my exact fee once you tell me the subject.
Finally, a warning: Wikipedia administrators sometimes come to spy on Freelancer. When someone applies to your job posting, check whether they have reviews about their past work. If they have no reviews, don't tell them anything.
Let me know if you have any questions.
