540758 Developing vrituremart features for Joomla

Project Description:
Dear Programmers,

We run a website on joomla using virtuemart.
We want you to develop three features on our Virtuemart system:

1)We have 6-12 products in our Virtuemart store system. At the moment we have currency conversion module to three currencies (USD/EURO/GBP), we want to cancel the currencies option and instead we module that will allow to edit the price for each product for each currency.
For example: Product A
- 10 USD
-6 GBP
-8 EUR

Product B
-15 USD
-8 GBP
-12 EUR

and so on to the other products.
So we can edit the price for each product – for each currency (without online currency converter)
2) When we receive new order we charge our customers manually, virtuemart is hiding the full credit card number except for the 4 digits of the card in the admin panel in joomla. We need to create a rubric near the last 4 digits with the full credit card number, and the option to delete the numbers (edit) after we charge the customer so it will remove the credit card number from the database and will save only the 4 last digits of the card.
Please note, for security reasons we do not want to save any credit card on our website. So after we charging the customer, and press on the button "Update" it will remove the credit card numbers (beside the last 4 digits) from Joomla database.

3) In our old website we have an option to choose color of product before adding to cart.
We want to put this feature in our virtuemart for 2 products. the customer can choose the color, and then add it to cart. (Black or White)

After you finish with the development of this module, we will also need you to give us the source code and explain how to install the features on the website (because we own more than one website and we will need to install it on future) This is very important.
YOU HAVE TO COMPLETE THIS WITHIN 2 DAYS MAXIMUM. If you can't, do not bid.
We will choose only professionals with previous knowledge of Joomla. We need it asap, if you are the chosen bidder we will provide you full access to our website.
