Halloween Ideas/ Fall Portraits

Hey everyone I was just working on some ideas for the upcoming fall season and I was wanting some of your thoughts. I am doing fall portraits for any family, couple or even children who want their photos taken. I was also wanting to know if anyone would like their children or friends that have children would like a photo session with their children in their halloween costumes? Any thoughts or ideas are welcome. I think I will create a day so everyone can stop by and have their children come in for pictures. The session won't cost anything and you have the option to purchase prints.
