Job offering?

So a couple of weeks back, this guy from New York told me if I could do a model of a LEGO soldier for him... and asked how much would I charge.... I said I could do it for free since I would probably enjoy doing it... Later that day he sent me an e-mail;

"We arent going to use it after all, not for the cover inserts but would you be interested in doing something for the announcement? I dont know how fast you can pop these things out in different poses and what not so I need to know if you could do a series of pictures for a comic strip?"

Unfortunately I had to reject the job offer, not because I didn't want to do it, but because I needed a special program called After Effects....
