Screen Safety S Logo

I require a logo for my Consultancy business which will be used on all stationary, business cards as well as on certificates and materials for the courses we deliver. My company provides safety consultancy and training courses and our work is primarily in Television (mainly Drama) but also other Creative Industries such as Film, Theatre, Outdoor events. I am looking for a modern, simple design. My company is all about offering quality media safety advice and training to a niche market and promoting media safety in a positive and passionate way. I am all about clarity and pragmatism when it comes to safety and want to ensure it is not a load of red tape, preventive or used incorrectly as an excuse for not doing something. I have attached some images (found on web or famous) that I like in terms of logo look as well as getting message across. I also have a website ([login to view URL]) which is a work in progress but it might give an idea for the image / theme / colours (although open to change) that I am currently using to promote my business.
