I have account in Wikipedia for years, and while I haven’t written much in a while, it would be obvious that it is old and non-spam account. (On Englisha and Serbian Wiki) I also handle English well, and would provide you with translation of the article to Wikipedia in Serbian, Croatian, Bosnian, and short article in Russian. So, you’d be getting 5 pages for the price of one.
However, you have to be aware that Wikipedia has its rules, and that article has to be written in non-advertising form. Also, in order for it to remain on Wikipedia, we would have to quote some some sources. (Are there mentions of your company online?)
And also, it is very important that your business/brand is of common relevance, otherwise, the page would be deleted.
