Do you have a talent? What about drawing? If you can draw "Caricatures" why not draw them for people at weddings. You can hitch a ride with other DJ's that have their business and customers already established. You can do many things with this. Either you can have the guests purchase the pictures and then give a percentage to the bride and groom, or you can even just get paid by the bride and groom to give these "free gifts" to the guests. Why not?
This is a great idea for someone who has talent and that is looking for a job. Why not do it on the side till the business picks up for you?
Here is someone that had the same idea: http://www.caricatureyourwedding.com/
