I wont lie, the pictures you attached are not visually appealing, but autoalert got a solid, coherent and minimalistic design approach. I think I can deliver you exactly what you want, but from my experience I would suggest like a friendly advice that you lend material from your physical office, like pics or small videos. There's nothing that can secure more a customer than having a corporative visual approach of who they're dealing with. But that aside, I am always online and available, since you have your ideas clear as water we can resolve this very quick. Good luck with your project.
