Leading Sydney Financial Services Company - Needs a logo (plus more to follow)

C'est ce que Dimension recherchait dans leur logo design

We need a logo (and symbol) designed for a new property finance company that we have established. We are a leading real estate agency operating for over 20 years, with 5 offices and have started a joint venture with a group to run our financial services division.
Dimension will offer initially offer mortgage broking services to be followed by insurances etc. The full company name is Dimension Financial Services, however will trade as Dimension.
It would be great to have a tag line also - Ie Dimension - Finance your Future (but not as tacky - PLEASE COME UP WITH A SUITABLE TAG LINE RELATING TO DIMENSION & FINANCE;)
Colours need to be White, Orange, Dark Bluen (attached) Voir plus
