So for a change can someone please help me

My church needs a digital projector for doing songs/notices etc and me being the resident tech, they have asked me to find them one

I know enough to get me by, but was hoping that someone else here knows a trick or two and could point me in the right direction.
OK for anyone that needs to know, the requirements are as follows:
- The setup shouldn't be uber expensive, but I still would like a capable projector
- Ambient light will be fairly high, like a standard daylit room. But not so that it would have direct light on or near the screen or anything
(What brightness should I be looking for?)
- Standard 1024x768 res will be fine
- Screen is going to be at max 8-10ft diagonal
- Throw distance is whatever, around 2m would be nice though
- It needs to be fairly portable, but is probably going to be installed on one of the hanging cage type things from the roof, so ultra lightweight isn't required
Erm, i think that should be all anyone could need to know, if it isn't then just ask.
I'd be glad if anyone knows some good guides that I could read to learn about this stuff too.
Thanks,
Dan
