We've been working with Kontrolit sites for our clients and our own businesses for 4 years now. The system is flexible and easy to use and the team are both knowledgeable and helpful. I'm not a techie and yet provide and maintain websites.
Paul gives so much expert advice here on the forums that you can tell he is a stand up guy who knows his onions. Get a look around the 4N site and you'll know if Kontrolit.net can do a job for you. If not, just ask Paul for his advice, you'll get a response that will make you glad you asked.
