I've never been a lover of stating something like "MD" as a job title on a business card.
Unless you're describing that you're in a certain part of the company (sales, marketing, export etc) I find it a bit unnecessary - a bit like using "Mr John Smith"
The other thing is that you want to forget about putting the 2010 thing on the back of them - this idea will get worse and worse the further we get into 2010 and beyond. Even if you have it changed to 2011, it still gives them a use-by date.
Finally, the "one-stop-shop" phrase is used a bit too much these days in my opinion.
Just my thoughts - others may have different ideas.
