its a sucker scam
sucker scam = technically not a scam because if you have above a room temperature IQ you would walk away. almost like a "stupid tax" or paying for under coating on your car
dont know how many people are going to fall for it for $50, thats pretty steep. I would do it for $10 and its 100% guaranteed. then make a friend in one of those baby magizines and get them to print an article about it.
you should have some science around it or some board prego lawyer who has a hard-on for fake websites would come after you
