333906 osC attributes button (Ajax)

Avg Bid (USD)
Project Budget (USD)

Project Description:
I have a customized bulk stock update script in my oscommerce shop's admin.
I want to add a "add attribute" button at the bottom of each product, near the active/not active text (see attached screenshot). I want to be able to add attribute/s to the product that the button is below it by clicking that button, on the fly, using ajax (without page refresh obviously).
My website has QTpro installed, programmer must be thoroughly familiar with the QTPro addon and an Ajax expert.

Programmer is required to email me a detailed changelog when the work is successfully done.

Just to clarify:
I have a page called "quick_stockupdate.php", you can see the output result of this page in the attached screenshot.
I want to add a button under each product.
When that button is pressed, 2 selection dropdowns will open:
1) Option name, to choose the option name, like Size/color or whatever.
2) Option value, to choose a value related to the name chosen in 1), for example if size was chosen then I will choose one of the sizes, if a color was chosen in the option name then I will be able to choose the color.
The option value dropdown must show only options that the product doesn't already have, for example - if a product has size 7, 8, 9, they shouldn't appear in the dropdown, because they already exist so they are obviously not needed.

Once the value is confirmed, it should be added to the db and shown immediately in the quick_stockupdate.php page, under the other available sizes as seen in the screenshot.

I hope I am clear enough, if you have any questions, please ask before bidding.

Skills required:
AJAX, Anything Goes, OSCommerce, PHP
