Photographer Needed for Engagement Party!!

Hi Vendors!! Hopefully someone can help me!

I'm looking for one photographer to take photos at my engagement party that we're having Sunday May 30, 2010. The party is a backyard event, formal casual in a very large backyard. The event should be about 5-6 hours, however I am looking for a photographer for perhaps the first 3-4 hours only to take pics of guest, decoration, food, detail, etc. I would like the pics on a CD thereafter. I am looking to spend between $30-40 per hour for a photographer. Thank you so much in advance!! Please Forum Message me if you can help!
