I am getting married in 6 months!!!

Most people would be freaking out given I have too many things still left to check off my planning list. I am trying my best not too. I think I am accomplishing this by the simple fact that my Willard, my beau, doesn’t freak out. He is a calm guy who doesn’t let things stress him out (that or he is very good about hiding it).
Of the things I am missing to check off my list are pretty important, photographer & florist. I have my dress (which I love), my venue, caterer (whom I will be having a tasting in February) and wedding party. I think I have a lot done already considering I had to change my venue because of budget concerns.
I think I have a pretty decent budget to work with, but with my starting my Ph.D coursework this Fall I decided it would be best to cut the budget in half and have a little cushion to work with for tuition in case I don’t get financial aid. Added to all of this money concerns is the fact I have a discerning eye for detail. I admit I like nice things, okay, really nice things. I blame my mother for this. Coming from a family of artistic persons, I have the tastes of a person with tons of money, which I obviously don’t have. This sometimes causes a good argument with my beau whom in all his reasoning thinks things should always fit in a budget and if it doesn’t then we don’t need it (damn mathematicians and their number crunching!)
That leaves me to try to figure out, What is a reasonable budget for wedding photography? I don’t want anything crazy, just some really crisp and elegant photographs of the wedding party before the ceremony, a few photographs of the ceremony, a few of our families and the food/dessert. The rest of the reception will be up to the guests, all of who I know are paparazzi and will most likely take tons of candid photographs.What do you guys think is a reasonable price for a photographer considering what I want?
I already have the florist in mind, I just have to call and schedule an appointment. *breathes deeply*
Here is to hoping I can stay calm and collected and find the right vendors. *fingers crossed*
