I'm all for volunteering and helping out organizations without funding. But and here is the big BUT. They are expecting a prospective entrant to do far too much work. They are giving far too many stipulations.
I'm currently helping out a daycare with there promotional material. They are not paying me. I'm doing this for a big thank you. Why? Because i like to help out when people need the help. Here is the catch though. It's done on my timeline and they are more than happy with that. I'm doing them a favor not the other way around. I'm gladly and happily helping them out, because they actually need the help. Any help they can get. They are not trying to fleece someone for a corportate identy kit with the guise of doing the designer a favor.
