Contacts: How to set up multiple versions of my contact info?

I use my iPhone for business and personal use. I wanted to share my business contact info with clients, so I've created a contact for myself with only my business phone, email and URL. I also have a contact set up with my personal phone and emails that I don't want to share with business clients, but that I can share with family and friends.

The problem is that Contacts insists on merging them into one, and adding the business info to my personal contact, because that's the email address associated with my iCloud account. I tried setting the business contact as My Card, but it hasn't worked. Any time I modify my info, it keeps merging.

How can I set up two separate contacts for myself, using my exact same name, that I can choose to share with different people for different purposes?
