Well summer is almost over now, but I would think starting off doing a summer day camp would be best. So your biggest problems there are that you need a location and legal protection. If the local University doesn't offer something like it, you could take to someone in the CS department and pitch your idea. They'd also have some of the resources you'd need like a computer lab, and then they would also do a good deal of the administrivia (fliers, insurance, etc.)If it has good results you might be able to convince the uni to take you on as some sort of employee. Best of luck!
