I need someone to modify the checkout part of the Virtuemart for Joomla (2.5) such that when someone wants to buy a product, all he/she would need to do is to
1. Provide name, phone number and delivery address. Have ability to leave additional comments. This will be used in creating an invoice that would contain the price of the products and the how to make payment and how the delivery would be made, etc.
2. When the cart is finalized and place order is clicked, one gets immediate email with “invoice” – a PDF document. This invoice is also sent to the email of an admin of the website to know who has placed an order and what the person ordered for.
3. The admin should also be able to see this via control panel and should be able to complete transaction by clicking on a button. This should then complete the virtuemart checkout process as if the person has made full payment and received the goods
