Take a look at other companies in your area. The price of a DJ is very regional. Just ask people in Nebraska compared to New York. Throw out the most expensive and the most inexpensive for similar services. The most expensive, if they have nothing to truly show for the added cost and the least expensive because of the worrying you will do leading up to your wedding to see if they are really trustworthy. Then make your decision based on who makes you feel the most comfortable and matches your requirements and desires for your wedding.
