I need a logo design suitable for business cards and also suitable for use on website

I am a Reiki Master Teacher and am starting up a new business. I am certified for Animal Reiki too. I will be offering Reiki to people, to their pets/animals and will also run classes/workshops teaching Reiki. I need a logo design that I can use on a website and also on business cards (I am thinking double-sided business cards - with one side highlighting the animal reiki service).
I am thinking of wording such as "Dermot Nolan, Reiki Master Teacher" and perhaps a tag line of "Relax. Rebalance. Transform."
