you going to wait and watch how many he does, even if you ask him he will probably say yes he does them all. I will be honest, if you came up and asked me how many I did, I would tell you its nothing to do with you.
If you are going out to a job, and are intending on doing it why would you give it away, you will be wasting your time. For all you know the guy only does one as well and even if he does do them all, maybe the customers where just waiting to get a hold of someone else, as the guy they have is crap.
It should be a competitive market, and if you cant make it worth your while, maybe you are charging too little. I will do to a job regardless of competition and anything they are doing.
