Now this is a method I've personally tried myself last year and it gave me good spending money for the following week. What you will do is offer to take pictures of people's kids for 5$, that simple. Last year I did this from my house , every person that rang I would give them candy but also offer them to take a picture of them and/or their kids. Process: 1. Get a decent camera to take pictures 2. Instead of spending money on a back-splash , decorate an area in your backyard with trees or bushes with Halloween decorations and spooky plastic lights. 3. Make the client fill out a form , asking for their name , telephone number and address to send the picture to. Now all you have to do is send out the pictures the next day. The decorations I bought were used and cost me 15$ in total. The camera was my mother's. I took pictures of 25 people , 25 x 5 = 125 - 15 = 115$ profit in a 4 hour halloween night.
