Drag'n'Drop Javascript modification

We are interested in hiring a programmer to add additional functionality to existing Javascript code from the following open source project: [url removed, login to view]

Two columns (A, B; column A is left, column B is right - see attached [url removed, login to view] screenshot).

Column A has 8 boxes (arbitrary number - we should be able to modify it later)

with 2 values displayed on them (lets call them W, V).

Every time a box is dragged from A to B the box id, elapsed time for the movement and box values (W,V) should be written to the database.

Additionally a display beneath column B should show the sum of W,V (separately) for the boxes moved into it (like a shopping cart - see attached [url removed, login to view]).

There should be a threshold (which we can change) for sum of values W and V. If one of these thresholds is exceeded additionally dropped boxes should be automatically moved back into there original position in A.

The W,V values should be read from a database table while initialization of the page.

I just checked the page and realized that the script is not available at the moment. I can provide a copy upon request.

We would like to see a working demo before payment (which will be done through an escrow account).
