Something for Nothing

Below is a posting that I cam across on Craig's List.  I found it to be, well, interesting.  As a sometime club DJ I am always interested in opportunities to DJ, and I have promoted parties at a loss just so that I could get in the door at a club.  However, as a mobile DJ I would never pay money to DJ.  It just does not make sense.  But that does not stop people from trying to get something for free.  In the posting below a couple is requesting a wedding DJ to play at their reception.  I understand being on a budget, my wife and I held our wedding in the backyard of her Dad's house.  Yet to ask for a professional to provide their services for free when you plan on having 200 guests....

This letter is for businesses that wish to branch out with new advertising ideas. We are thrilled to be getting married next year on August 30th. We have been together since our teenage years, now going on 6 years, and wish to start off our lives without wedding debt. I just graduated SDSU and am excited about my next venture and opportunities in life. My mom always dreamed of making me a fairy tale wedding but as a single hard working woman it has been difficult. Any help, products or services from you would relieve her of the pressure she is under. We will be having many of our young friends attending who will be great potential clients. I am well connected in my community through work and social events and would be thrilled to spread the word of your good deeds. How would you like to sponsor a portion of our wedding and reach new, exciting advertising avenues? This will be a large wedding with over 200 guests. We can discuss ways to promote your company if you partake in a part of our day such as limo, food, flowers, photography, videographer, linens, favors, chairs, chair covers, balloon or any free standing decorations, gazebo, DJ, etc. This will be a win-win situation for all involved. Not only will you showcase your fantastic work and /or products but also get the praise for it. You will be attaining priceless advertising for the day beforehand, during, and afterwards. Thank you in advance for making our day the best it could be.
Sincerely,
a very hopeful and optimistic bride
