Good audio visual providers can make or break a conference

Finding a good (Audio Visual) AV person is like striking gold. The AV can make or break a conference. You want it to be seamless, and if it goes wrong, it's highly noticable (since that's what everyone is looking at!) Be aware that there are lots of different options, and AV providers should be able to be flexible to meet your budget. Some places will go in (very) high, and then the onus is on you to work your way back to something more reasonable for your client. There are options like Skype out there these days as well - make sure you ask about it. J ;-)
