Looking for JQUERY and HTML5 front-end developer to build "Floor Plan" editor

I am looking to develop a floor plan editor, written in HTML5 and JavaScript/JQUERY. The floor plan editor allows the user to build a replica of a room interior. This is done by allowing the user to select from a list of objects (such as tables, chairs, etc) and to drag and drop those objects onto a canvas. Once dropped onto the canvas, the objects can be selected, resized and rotated. Once the room is laid out, the user can save the layout to a JSON datastructure. This same data structure can later be used to reload the room layout. Detailed requirements: General: Must be responsive in the sense that it should work on desktop browsers as well as all major mobile browsers. Code must be production ready code, cleanly written. formatted and separated into files. Canvas Object: The canvas serves as the container for all room objects. Canvas can be zoomed in and out either with on-screen zoon slide, mouse wheel or pinch gestures on mobile. Canvas state along with all object placements properties should be save-able to a JSON data structure. Canvas should have the ability to be loaded/restored from a JSON data structure. Canvas can have a grid turned on or off. Grid can be resized with a slider tools. The purpose of the grid is to facilitate "snapping to grid" when placing objects onto the canvas. Canvas has two modes. First mode is "Edit Mode" which allows the user to build the room. Mode two is "View Mode" which allows the user to click on objects that have certain tags, i.e. stencils tagged as "selectable". The purpose of Edit Mode is to allow admins to build the room. The purpose of View Mode is to allow customers to interact with the built floor plan and to select certain objects. Toolbar: A floating on-screen toolbar provides access to commands including "Save", "Revert", "Toggle Grid" and "Snap To Grid". Toolbar should be easily extensible to add more commands. Palette: A floating palette shows a list of all available room objects, aka "stencils". Palette has a "Category" selector (drop-down, perhaps?) that allows the user to switch between "sets" of objects. I.e. "Wooden furniture" or "Living Room Objects", etc. Palette objects and object sets should be defined via JSON data structure Stencils: Stencils are selectable from the palette and each stencil represents one object. Stencil data definition should include a reference to its visual representation (i.e. the image location) as well as additional ad-hoc parameters. I.e. I should be able to tag a stencil as being "a chair" or as being "immobile". with samples. To know you read all type"xdream" in [login to view URL] placed on the canvas, stencil should be selectable individually with mouse click or finger tap on mobile devices. Multiple stencils can be selected with rubber band selection on desktops. Once selected, stencils can be moved, resized or [login to view URL] contact me Need sample links to previous job done with HTML5 and JavaScript/JQUERY.
