Hi!
My name is Andrea, I have a degree in Communication, and more than 10 years of experience working online. I edited Wikipedia articles in Spanish for 9 years, and in English Wikipedia for 3 years, therefore, I am totally familiar with the platform.
Actually, nobody can modify a Wikipedia page if he does not have enough evidence to do so; in other words, they must have reliable references. I suppose that if other people could modify your page it is because they contributed the corresponding references. Take into account this information to face your project, you must have reliable references, from secondary sources - texts produced by the company are not accepted -.
If you wish you can open a parallel project to this one, for USD 20, and I can advise you about it, if you send me the link to the Wikipedia page and the references to include.
Do not hire me for USD 750, it's too much money. If we can do the work, it will be for USD 15 per hour, if you agree.
Thanks !
Andrea
