In most of our ads, PsychologySalon is the format: Cap P Cap S, others small, and all one word. If it seems to work better to split the words, fine.
Some thoughts: People think of couches with psychology, which is a bit old hat, but done in a fun way might work. Also, the greek letter psi is commonly used as the symbol for psychology. These are vague ideas only, not requirements!
Our target audience is 25-45 urban professionals in Vancouver and elsewhere interested in self improvement. Most are fit, outdoorsy, high achievers who are often overwhelmed by their lives. A bit of the Vancouver yoga crowd, but not overly involved in the New Age (crystals, horoscopes, etc). People interested in reputable, no-nonsense suggestions for making their lives more workable.
The design could simply say PsychologySalon, or could incorporate ".com" as a small tag, showing that there is an associated website.
Thus far we have used a photo of a bowl of cherries as our theme picture for many ads and the start of each presentation. Attached. Not necessary to incorporate; we just liked the "life is a bowl of cherries" idea at one point.
