Transitioning to bottle

I will be returning to work 3 days a week. My baby is 3 weeks old. When do you think I should begin working on a bottle relationship? Are there any recommended slow flow bottles? Am I right in thinking if he is at care from 730-330 I should prepare him with 3 bottles of 3-4 oz of breast milk? And I should pump 2-3 times during this time? I’m confused on where to begin. I want him to successfully take a bottle before daycare (he will go right after new year) from myself, dad and others so he is fully prepared for the transition. Also, I may choose to drop a night feedings on weekends and give it to my husband. I also may occasionally call upon a weeknight or weekend evening out with friends as he gets a bit older. Any tips or advice is appreciated.
