On Premise, not Cloud need inexpensive method of analysis of facebook thumb pics

I need a method of scanning over 400 000 pics and see if it can determine gender, race and approximate age with some accuracy. The source code must be provided and person would write code would determine these three values (gender,race,approx age) and place in variable so I could put in database. . I would strongly prefer if I can call this code in C# so I can easily take your values and plug into my Microsoft SQL Data base
