Welcome.
I would start off with showing your dog at shows. Nobody will want to use him if they don't know he is around. Shows are where people go to show off, compete, and work there Bulldogs. It is a start. Second there has to be a reason to use your dog(not color). Like pedigree, hip scores, or titles on the dog. If I was you I would go to shows with him and bring his pedigree and show him off. Or I would buy a female.
Question for you is why do you wont to breed him?
