Bad idea for many reasons. Starting a business and selling snakes is your idea and you should receive all the credit you earn. I have heard of many business horror stories of business with family. Its very tricky and can turn families upside down.
Also I think you are seriously under estimating business and business aspects. There is a reason people go to college for 4 years to learn this stuff. I'm almost a sophmore and a business major and its not easy, and there is much to learn.
