540143 Adding features to Virtuemart Joomla

Dear Programmers, We run a website on joomla using virtuemart. We want you to develop two features to our system: 1) We have currency conversion module to three currencies (USD/EURO/GBP), we want to change the way its converting currencies (actually it should not convert the currencies, only show fixed price we have set up for each product) What it should do is: We put a fixed price for a product in our store, for each currency, Euro / USD / GBP (for each currency we have the fixed price) so When a customer the customer change the currency and add it to cart it will show him the fixed price we set for the specific currency 2) We charge our customers manually, virtuemart is hiding the full credit card number except the 4 digits of the card in the admin panel in joomla. Please create us a rubric near the last 4 digits with the full credit card number, after we charge the customer we will press on "Update" and it will remove the credit card number from the database and save only 4 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 from Joomla database the credit card and save it only with 4 digits. After you done developing it, you will need to give us the source code and explain how to install the features on the website (because we own more websites and we will need to install it on future) This is very important. 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. Thank you,
