I have to agree with the ladies who say don't offer a free day of daycare. If you do that, you may end up with everyone referring just for the free day and not because they actually think their 'friends' child would be a good match to the program. Most of my referrals have been fabulous and worked out well, but I've also had one woman refer her friend and then ask me for a family discount if I take her friends kid...seems people will do anything to save a few bucks!
