Transitioning from breast to bottle?

I have a 6 week old baby and I’ve been exclusively breastfeeding since birth, from the breast only so far. He will need to take a bottle soon but every time I try he refuses and gets more worked up and hungry. I’ve tried fresh milk, warmed milk, different nipples, different people doing the feeding, and still nothing works. Can anyone give me tips on ways to help him accept a bottle? Maybe any bottle/nipple recommendations?
