Weddings...how much is too much: photography

So wedding planning definitely ain't as hard as it sounds...not if you have a tree that sprouts money in the spring that is!!! The prices of wedding vendors are more than what some couples receive in gifts for the wedding. I've got a DJ, now I'm looking for a photographer & videographer (didn't even know the word/occupation existed until this search began) and I'm curious how much is too much? Yes, it's very important because you want to have these memories for a lifetime, but is it work paying $7,000?!?!? In case you're wondering that is an actual quote someone had the audacity to send me! Please chime in w/ your opinions & suggestions...because this is a mind boggling subject.
