I don't put a title on any of the cards for my consulting or startup business(es). They tend to be over- or pre-loaded with meaning, frivolous, meaningless, and/or limiting, esp for a solo/small operation.
Try this:
On the face: Name, pho no & email addr.
On the back (opt): Company name & catchy, descriptive tagline.
Use an interesting, legible font.
Keep the color scheme simple.
A well crafted tag-line is much better than a title, and gives you a lot more freedom to market yourself, your services/products and your business.
I get a lot of complements on the simplicity of my cards, I save # on printing costs, and there is plenty of room for potential clients & customers to make their own notes about what they want to follow up with me on.
