Someone on this board recommended Jerry Binder. I would do a board search for reviews.
Good luck. We were unable to find anyone who would do it for less than $2,000. We didn't want a video with all of these special effects, highlight reels, music dubbed in, etc. Just a straightforward video of the ceremony and second line. So, we ended up just asking a friend who has a video camera to sit in the front row and film it. It's not what I had my heart set on, but we didn't have room in the budget to pay that much and get a bunch of services we didn't need or want.

Agree with pp that I found it very difficult to find a reasonable/inexpensive videographer (with recommendations) for a more basic video product. In the end, I chose My Bella Video/Films and by the time I got around to convincing myself to pay this much for a videographer (I will say I was shocked at how much these cost....I had NO idea!), they had gone up in price. Ugh! I hope this is worth it.
