Hiring a non-Muslim artisan instead of a Muslim

There are two artisans I can deal with, one non-Muslim and another Muslim, the non-Muslim goes out of his way to give us excellent service, with good prices etc. the Muslim unfortunately does not offer excellent service we have chosen the non-Muslim but the thought crosses our mind that is it the correct thing to do. I mean ignoring Muslims and giving business to non-Muslims rather. I also give Dawat to him sometimes on the phone or maybe with paying on time etc. What is the respected Mufti Sahebs advice in this regard?
