Evernote image search API integration plugin for Wordpress with WPEC extension

PROJECT GOAL
I need to develop a wordpress plugin to allow my website visitors to make searches in the images I posted in Evernote. The plugin will use Evernote Cloud API.

In a second time, the visitor can add a product seen on an image note to its cart and a small personalised description to the product.

SEARCH BOX (Evernote API)
A [Search box shortcode] can be placed in any page or post. Advanced search and filters (like in evernote) must include at least date and notebook's name. The search will only apply on evernote notebooks using evernote API (no wordpress content search).

SAVED SEARCH MENUS
A saved search menu can be placed in any page or post with a shortcode [saved search = ID]. When choosing an item in the saved search menu, results are shown according to keyword’s item (for example : clicking “blue color” in menu will search for keyword “blue” in evernote)

WIDGET
There will be a widget for Saved searches and search box.

RESULTS (Evernote API)
Results must be shown as thumbnails grid or list view with note's description.

When clicked, image is zoomed to all screen or 100% (original size from 1800x1200 and above). Navigability must be intuitive to move on image surface details (for example dragging image with the mouse). A tool area also offers a switch icon to show (default option)/hide results boxes on image (using evernote API and CSS to highlight results) and 2 arrows to show next/previous result images.

[results shortcode] can be placed in any page.

ADD TO CART IN ZOOM MODE (WPEC API)
The website will work with WPEC plugin. The customer can order the product seen in zoom view thanks to the “add to cart” button from the tool area.

When pressed, the “Add to cart” button ask for an extra description (personalization field in 'Advanced Product Settings' -> 'Personalisation Options' and enable 'Users can personalize this Product by leaving a message on single product page'). There is only one product SKU with a unique price. At any time, the visitor can add a product (with its own description) to its cart .

The description field will also record evernote reference + notebook name + date + searched keywords
