Swans is pretty **** for breastfeeding support, so I don't find that surprising, unfortunately. I'm not sure it has anything to do with the socioeconomic status of women in the area, so much as a complete lack of emphasis on breastfeeding support and education.
I found the midwives there are really good, but didn't get a great impression of the few OBs I met. The one who helped deliver DD seemed alright, but the others....

Anyway, I suggest you arm yourself with literature, a strong will, written instructions for your carers and a gatekeeper - someone who can stay with your baby if you can't and make sure they do what you want them to. Good luck and hope all goes well for you.
