Virtavia is currently working on a Mil Mi-24D "Hind", and Nemeth will allegedly be working on an Mi-24 as well, but I am not aware of the variant, and am not aware if there is a connection to Milviz in there.
The aircraft the OP highlighted seems to be a project that simply modifies one of the existing FS2004-era models.
