You didn't send me your email address so I will post this for you -
Congrats on your engagement!!! I booked Full House about 16 months in advance. You can check out their website www.fullhousemusic.com they also work through a company but I hired them outright. I think we are paying 4500 but I dont have my info in front of me. They will work with you depending on what you want - cocktail music etc.
They are definitely amazing - I have seen them a few times now out and about on LI and I love them!!
