Logo Design Brief
My company has two marketing branches to sell our properties: (1) TopazWholesaleProperty.com
(2) TopazRentals.com
(1) is to sell investment properties to other investors
(2) is for rent / rent-to-own and / or seller financing to the retail market
I need a logo for both - to put on each website and corresponding marketing signs. I would like the two logos to have a common theme so that they are clearly from the same source, but distinct enough that one is not confused for the other.
Also, the logo layout should be conducive to a sign which is usually a ratio of 1.3 to 1.5 (width) to 1.0 (height) (i.e. 4'x3' or 36"x24")
The sign needs to have a room for a phone number in big, visible numbers at the bottom, and some type of banner across the top that says "House for Sale" or "Available for Rent" or something similar. With the logo and website in the middle. The point being that the logo needs to be a "landscape" layout (not a "portrait" layout).
Since the primary usage for this logo is for the website and for signage - using the name of the website in the logo is required. The overall impression should communicate financial stability and trustworthiness. I don't anticipate a lot of extended graphics - the focus should be a clearly visible and readable website address with some supporting "flair" that makes it a logo instead of just a string of letters.
A sign design does not need to accompany each logo, but if you could include a basic design (as described above) to help provide perspective, that could be very helpful but not required.
I have uploaded two other logos for other company's I have. These logos do not need to be similar in color or design - but just to illustrate the type of logo that I'm looking for.
Updates
I should mention that I understand that the two websites are very different in length. I also own the domain: TopazHouses.com which could be used in place of TopazWholesaleProperty.com on signs. This would also provide more similar display dimensions to TopazRentals.com. But this is only as a backup option if TopazWholesaleProperty.com is just too big to look right.
