Dear kyra,
first of all I wish good luck. If your wedding is in December you should notice that the date is not too close to Christmas because there are many parties and DJ's will take more money. In addition you should pay attention that many accessories are more expensive only because they are for wedding. If you want to know how to save more money on your wedding and plan the same wedding you want you might want to take a look here
