If I were a Schnauzer bitch owner looking for a stud dog, these are just some of the questions I would ask which aren't answered on your site:-
1. How old is the dog? - I wouldn't look at using a dog under the age of 2 (minimum).
2. Has he been successfully tested for all the conditions recommended by the breed club for the breed?
3. How does he measure up to the breed standard? What level has he been shown at and what have been his successes? (The successes of his sire are no guarantee that he will be of similarly good quality - and two shows, one of which appears to be a Companion Show does not constitute a successful showing career

)
4. How compatible with his pedigree is that of my bitch? (In other words I would need to see the full pedigree of the dog)
5. Have any endorsements placed by the breeder of the dog been removed so that any resulting pups can be KC registered?
6. Has the dog been used at stud before? If so, can I contact the breeder who used him?
I'm not trying to be picky, but these are some of the genuine questions I would want answering before I decided to use any dog at stud.
