Bitcoin Payment Gateway & API

We need a well designed custom bitcoin payment gateway/ interface and API. Installed and tested on a website.

Functions must include:-

1. Very easy customer friendly payment interface (similar to Gourl) with the Gourl functions especially with copy wallet address function and open both local and web wallet functions and QR. Must look professional and attractive. Must look professional, original, attractive ,responsive and work on all devices.

2. Unique Btc address for each transaction using blockchain (all sending immediately to our specified blockchain wallet)

3. Secret key / API key etc and full security

4. Must take a variable total from custom shopping cart and display the cart total (amount to pay) in both USD and in the exact current exchange rate to BTc .. showing the correct amount of Btc to transfer. Should hold flat rate for 10 mins.

5. Must provide a clear and well designed callback confirmation of payment (in same page or on new payment confirmation page as an option) (preferably and if avoidable not irames as they don't display well on mobiles)

6. Very importantly and AFTER payment/ callback function must update site database and trigger auto customer transaction confirmation/ order emails.

Basically we need an improved version of the Gourl Bitcoin payment box/ gateway which sends 100% of the payment direct to our named wallet and NOT via their system ..

To fully understand what we want it is recommended you visit Gourl Bitcoin Payment Box and set up a working demo so you fully understand the functionality
