Recommend a camcoder model based on my specific purposes

I've been looking online for weeks, but still am boggled by the many choices out there, and am looking for specific recommendations so I don't end up with a camera that doesn't fit my needs.

Compounding the problem is that I'm in Korea, any cannot communicate effectively enough with salesmen at camera stores, so I'm really relying on internet discussions for a sense of what I need. So any input would be greatly appreciated!

SHOOTING LOCATION:

I will be shooting teaching videos in a very small room. Will use a tripod with very little camera movement. Mostly shots of myself at a green marker board. Will rig up some lighting.

DELIVERY:

After editing the videos (simple cuts, titling, music) in a program like Sony Vegas, I will upload them to YouTube and other free file hosting sites, as well as to my own website. In time, I hope to be able to create a subscription service, so the videos should have a commercial look. As well, I hope in the future to compile my lectures onto a DVD that I can sell. Until that point, though, I do not need any hard copies of the lectures, so I have been looking at hard disk cams.

NEEDS:

I don't think I need any special bells and whistles (zoom, high-speed motion capture, etc), just a high-quality picture that seems very professional, as well as clear sound (which I worry about in such a small room; I'll have to cover the walls to reduce echo). I'm not sure if there are certain models that faciliate editing and internet publishing, but if so I guess I should be looking at these. I'm also unsure as to whether or not I'll need a mic jack and wireless mike in such a small room, or if the camera's internal mike will be able to capture my lectures clearly enough. I'm torn between recommendations for HD and miniDV.

That's a summary of things so far. What kind of camera can fit these needs? I'm looking ideally in the under-$1000 range, but think that for my very simple purposes I could get away with a cheaper model. Thanks for your help.
