Design a Website Mockup for a web configurator

Have you ever set up a router or used a web configurator? That's what we are looking for. In this project it is required to create all the web pages required to manage all parameters of a web configurator running in a small-embedded device, which acts as a gateway in an installation. We are a top level engineering company selling design oriented products so the design of this web configurator must be according to this. The responsible must design and create the webpages and carry out the validation of the input data on the front-end, but... THE PERSON IN CHARGE OF THE DESIGN IS NOT RESPONSIBLE FOR PROGRAMMING THE FUNCTIONALITY OF THE WEBPAGES. Example: If a user sets a parameter in a text field, the responsible must verify the parameter so the type is valid, but he/she does not have to store it within a database nor develop any kind of internal logic. The Tools: It has been proposed to use and respect the following standards and frameworks, however if the responsible demonstrates a better option, it will be assessed: HTML5 CSS3 BOOTSTRAP (OR ANY OTHER CSS FRAMEWORK) JQUERY NOTE: All frameworks and packages must be loaded from a local folder. For security reasons it is not allowed to download the packages from external repositories. The Pre-Requisites: The work has to be original. The webpages must work in most of the existing web browsers paying special attention to old versions of the Microsoft’s Internet Explorer. This web configurator must run in IE 6.0 or later versions. Be careful with GPL/GNU licenses. This is a commercial product!!! There must be a validation on every input field. The validation could be "something required", datatype, length or all of them. There must some menu to jump between the web pages. It is required to provide a couple of error pages: 404 (page not found) and 500 (internal server error) Responsive and stylish design. The configurator must be accessible from the latest architectures (smartphones and tablets) We love dark colours, but we are open to new designs and styles. It is mandatory to show a previous version of the design (not all webpages) and colours selected, before going ahead with the project (The use of tools like balsamiq mockups and photoshop is a plus) We are open-minded and we like to hear proposals from imaginative people. You are the expert...demonstrate it! This is a really easy job for someone with the desired skills and initiative. Please do not bid if you do not have a 5 stars rating or you have an empty portfolio. Freelancers selected in a first round will receive further documentation and among them we will select the winner. Thank you and happy bidding
