Very difficult question.,Good hazerat?? Send your child to the Auqaf Quran Centre nearer to your home and they will pick up kids in their transport and drop back home safely, but looking for a Good Hazerat, you have to make cardiologic approach of each Hazret's private, personal life status to know the digree of his Thaqwa above the skill of reciting and teaching of the Quran. There are many nationalties and they have all different type of efficiencies and style in teaching, but Marqaz, thaeleemul quran follow the standard form acceptable to everyone and is better. Dont allo any Hazerat to come and do this job in your private house and it is not safer because all shaitan except the Shaitan of Prophet Mohammed alaihissalaatu wa ssalams, is still not become muslim. He will take advantage of good facilties to turn into something what you dont expect it if allah not protect him even if his profession is very honourable. May allah guide you to right place for your noble intention.
