Online 3D Configurator and price generator

General information for the website: Site for business that builds Garden Rooms Description of every page/module: I require a 3D configurator developed that will have functionality very similar to this: http://my.greenretreats.co.uk/configurator/index.html Description of requirements/features: I will provide a set of Photoshop Documents for the user interface design for both desktop and mobile, the configurator will need to look exactly like the interface sent and be fully responsive. Extra notes: Feel free too ask any questions you may have. There is no rush on this project as it will need to be perfect :)
