Normally I'd suggest posting on the local board, but being a Vermonter myself, I know how lifeless that board is.
I won't be a big help because I have a DJ in the family who's doing mine, so I didn't have to research. If she lived around here I'd recommend her in a heart beat.
Do you want someone who's a very experienced professional in the field? They can get pricy. I went to college with a couple people who do DJing as a side job. They're both really good, and have equipment. One of them is more experienced than the other, so I would recommend her first. As far as I know, they both have facebook pages. If you want me to look into that for you send me a PM and I can give you more info. I wouldn't mention it if I wasn't confident that they'd be great.
My only other ideas are to just start google searching and contacting people. It's a bit tedious, but that's how I've found people for other things. Do you know anyone that's gotten married within the last couple years? They might have recommendations too. Good luck!
