Agree with Suffolk re. expressing fairy, it can be really really hard!
Initially it is not a good idea to express for one bottle per day - you would want to wait 6-8 weeks until Breastfeeding is established as your supply could be affected. In the early days, if you skip a feed you would really need to be sitting expressing anyway as you would be very uncomfortable, so this defeats the purpose of you getting a break 
My dh occasionally gave dd a bottle of expressed milk on a Saturday or Sunday morning so that I could have a long lie. We didn't do that every weekend though (probably once per month) and waited a few months before starting this. But it was wonderful as I would give dd the 5am bf and get to sleep until 10!!!!!
We did take bottles of expressed milk to a wedding when dd was 8 weeks old as my dress was not Breastfeeding friendly so we needed a back up for the ceremony and meal. In between I went to a room to feed as I literally had to whip my dress off! My boobs were massive though and sore and I probably wouldn't do this again so early on. Next time I will find a decent top or dress.
Your dh can get involved in so many other ways - my dh always have dd a massage at bedtime and was involved in every other aspect of her care.
And it all depends on whether you want to give formula once per day too - we didn't want to use formula at all so if I wanted to go out I has to express. And after a few months I did have nights out with friends, i just had to be told in advance so that i could express! Initially I would get hundreds of milk out bit after a year I got literally nothing at all - absolutely nothing
which was ok by that point but some women find that they get nothing or very little when expressing from day 1 - but that is not a reflection of what your baby is getting as they are way more effective than a pump.
I actually went away for 2 nights with friends when dd was 9 months old and expressed 60oz of breastmilk beforehand! But that took me a couple of weeks 
Oh and agree worth Suffolk re. hand expressing - it's a good idea to look into this before baby is born as you may find you may need to express precious colostrum in hospital if you have a sleepy baby. (Dd did not feed until late on day 3 so I hand expressed colostrum and fed her with a small cup or syringe)
This probably hasn't been very informative fairy, just wanted to share my experience!!
