Real Estate Logo

We are looking for someone to design our Real Estate logo. We have a very good idea of what we want and will provide you with a sample of what we are looking for and feedback as far a colors and layout. This is our first posting on freelancer but are willing to work with a professional who will provide fast service and quality product. We would like suggestions on how to properly deliver the finished product since we will be incorporating the design on everything from business cards, stationary, and even on the side of a large moving van, so we have to have the ability to easily pass this logo on to our other vendors in a easily transferable format. We would like a minimum of 3 revisions including colors. We will pay 100% at the completion of this project. Thanks in advance for bidding!!
