Modern Asbestos Surveying Logo

I'm looking for a modern, typographic logo and favicon for my asbestos surveying business. The color scheme should be navy blue and orange. We are called Fortress Asbestos Surveys and would ideally like an F as the favicon - possibly similar to the draft image attached...
