Supposed to be an engineering company. But they're scared of one of the best pieces of engineering. The camera. Avoid these guys and use a company that embraces engineering and technology.

Poor management. Watched a video showing the owner insulting a member of the public legally filming outside of their yard. Not a great ad for the firm. Look it up on YouTube and see for yourself!
