Start up Real Estate Agency needs LOGO

C'est ce que Coulson & Co. recherchait dans leur logo design

We require an eye catching logo to be used on all of our marketing-
Website, business cards, Signboards, shop signage etc

PRIMARILY AFTER A PURPLE BACKGROUND and Main use of Purple, Black, and dark grey to white tones

Really like the use of colours on this website:

Logo should be banner shape, approx 4x as long as it is high
It would be good if it had some sort of symbol incorporated that could be used by itself for advertising
