Virtuemart Sales & Profit Report for customer

Project Description:
First about the website.
Its like a webterminal for Shop Owners to Buy and Print Calling Card Vouchers through Internet.

They have an prepaid account which they must load with money and print the calling cards.
For every shop owner we will create a shopper group and add the prices for them. So every user get his own price but the value of the Cards are always the same.
We have done it with Joomla Virtuemart and made an modul to handle the PIN Code and Credit Managment.

Now we need to do some modification.

Scope of Work:
1. Add a date picker for From and To date.
2. Once the logged in user choose that date, display the transactions in a table which take place between that particular date.
3. Add a Total of Sold and Margin.

Its really not difficult because all Data is saved in the Database, you have just to fetch and show tha data in a table.
the table should be printable as pdf. (Joomla has a integrated PDF creator)

For more infos just pm me..
Thanks
