I actually have two professions
1. I am a WEB PAGE DESIGNER and have my own brand for WEB services

2. I am a TRAVEL PHOTOGRAPHER and have a separate website for my Photographic portfolio.

Now i need to make my Business Cards. But I am so confused. What should the card be like? Shall i make 1 card or 2 separate cards?

The problem lies that if i have 2 cards, and give one card to a person, that means I have lost the client for the other business.
So what PROFESSIONAL idea would be there ? or if you suggest me to go for 2 cards, then how?
