Don't search for the name. Search for the appearance.The identical font or almost identical font probably exists for free somewhere on the web but under another name. From Wikipedia
United States law does not permit the copyrighting of typeface designs, while allowing the patenting of unusually novel designs. Digital fonts that embody a particular design often become copyrightable as computer programs. The names of the typefaces can become trademarked. As a result of these various means of legal protection, sometimes the same typeface exists in multiple names and implementations.

, the most well-known being Arial.
Incidentally, if a search seems to be going in circles, it might be because traditionalists still refer to different families of type as typefaces. To them, "font" means the differences within a type family. Helvetica is a family, but a Helvetica font would be Helvetica bold, Helvetica italic and so on. Searching for "font" on a particular site might get you nowhere.
The larger "families" include serif and san-serifs. The typeface you want is a san-serif, a sort of squashed Helvetica bold — "Helvetica Bold Squished."
might make the search easier.
