Well, I used to be a videographer, so I may have some suggestions for you.
I would use 2 cameras (personal preference of course) and have one on standby mode in the back and on a tripod. Have it facing towards the altar in a wide shot, enough that you have the entire wedding party in the shot. You can prepare this the day before at the rehearsal so you know where to set the camera.
And just a suggestion, but if you want footage of your entrance, I would have someone stand at the camera and have them follow yourself and your bridesmaids going down the aisle and then set the camcorder in place for the rest of the ceremony.
With the second, I would ask a friend to get some personal shots, such as close-ups during the ceremony and if you want any footage of you and your fiance getting ready beforehand.
I would just use one camera at the reception, unless you want multiple shots, such as if you want a lot of dancing on film but want close-ups and other angles as well.
Keep in mind, the 2 cameras are so you have more than one shot for editing. Also in case one camera gives you problems, you have a backup filming as well.
If you have 1 camera, you would have to keep in mind (especially if you have a photographer) letting them have free reign to go wherever they want for different shots. For instance, from certain angles, it may be difficult to film a candle lighting or special speaker.
I’m sure you could find a videographer or a media student who would be more than willing to do the editing for a reduced rate. My father didn’t film my wedding, but he’s doing the editing himself, so the videographer worked for about half price.
I don’t really have any advice about cameras, but I believe we used Canon. I would just do my research, maybe look at a few videographey websites and see if they mention what kind of camcorders they use, and go in to personally try the camcorders in store.
I hope I helped.
