I've just been to Spain and this is what I did when I bottle fed Mia.
I didnt even sterilise the bottles as we dont have a microwave in our house there. I washed everything in boiling hot water first, then filled the bottle up with half cold water (mineral water as I dont drink the tap water there) and the other half with boiling hot water out of a kettle, then I'd add the formula powder to it. That was the exact temperature she'd take it.
When I am feeding Mia a bottle in Holland, I sterilise everything in those ridiculously overpriced contraptions you get

, 2 at a time usually, then add cold water from the tap to the bottles in advance. All I need to do is put them in a bottle warmer (which heats up the bottles to exact temperature in 1 minute) then add the powder to the bottle. Will getting a bottle warmer make things go quicker for you?
And who gives a rats ass about whether you breastfeed or not? I dont get why people feel so guilty about not breastfeeding??? It's a time consuming process, Mia is currently needing to be breastfed 10 times a day at least, which sometimes wears me down, but I dont mind plodding on with it. If it isnt for you, dont feel bad about it!!!! have managed to get her to take 2 bottles a day, just to give me a break - and I feel not a shred of guilt. Look girls, your babies are luckier than most, do you think they care where their food comes from? Be it a packet or a boob? I think not.
