Virtuemart + Joomla website - Modifications only

Currently have a joomla website with virtuemart integration. I need the following done. 1. Bring checkout process to 1 page. Checkout should probe for shipping on both regular and digital products at all times. 2. Currently accepting credit card payment and paypal. After payment custom email should go out in addition to the standard order confirmation email. This custom email has to do with sending the client download details of the digital product purchased. It should auto generate the email after payment confirmation and it should include link to download the product purchased. This should happen in both regular paypal payment and also CC payment integrated via paypal api code. 3. Some minor modifications such as adding paypal logo, text modification, submit button modification and text addition in the checkout screen is required. Should be able to get the job done fairly quickly. Looking to get this done in the next 2 to 4 hours. So only bid if you can get this done ASAP. Note: To keep spam and automated messages out, Please ensure you put in your comment "TEDDY" to let me know that you read this project and are able to get this done in 2 to 4 hours.
