Flying with my dog

Hi all.
Am hoping there is someone who can help me here. I live in NYC and plan on being in the UK for 6 weeks starting this December and I'd like to take my dog.
Would anyone know whether the process is painless and straightforward, or whether there are any companies that would take care of it for me? (NYC end only). I'd collect her at LHR. She is not qualified to travel in the cabin, only on domestic flights so would need to be in the hold.
I know she can travel on the VS45/46/111/112 but am specifically looking to have the time alleviated from my schedule.
Any guidance would be appreciated.
