There is this shopping cart http://btshost.net/cscart

The task required is to add a date search to the search form.
The cart is done is a cms called cscart - http://www.cs-cart.com/

The client required a feature like this:
I add maybe a Samsung phone, and i also specify the year that it was made in 2006,
so that a client can also search by specifying samsung phones between 2000 and 2006.

To do this, you need to add a year dialog or whatever to the backend form, and add a year
dialog or whatever to the frontend form.

If you feel you can do this, please send an email to support@.net specifying
your price and how long it will take you to do it.

Thank you all for your prompt responses. I am still expecting more responses.
