Looking for logo design for residential real estate brand

Hello – I am looking for an experienced logo designer to assist me with a logo/font for my real estate brand. This company will be directed to the luxury residential real estate market in my area therefore the logo MUST BE: Minimalist, modern yet elegant, classic & classy. It must appeal both male & female clientele and be professional. This company image must be able to be used in email signatures, Twitter accounts, Facebook page, website, iPhone app, etc. Therefore, I will need the image in different formats and something that will come out well in both web and print. Please note: I do not want ANY HOUSES in my logo! Please email me directly with more info including the name of the company and samples of what I like. I will only accept bids that: 1) Provide samples previous logo design work & at least 2 references with name of contact, company and a method to contact the person 2) Are custom – no generic logos/templates allowed 3) Would prefer at least one mock-up (mock-up can be protected w/watermark, etc) If mock-up is not possible, I want to ensure that the winner bidder will be ok with revisions from me as requested. I know I might sound demanding but this logo is very important to me as it will reflect me and my company for years to come. Please PM with more info about my company, samples of what I like and if you have any questions. Thanks
