Change To Checkout On PHP Website

I have a website, but need to change the checkout flow to as follows: 1. Currently all shopping basket items and delivery/invoice address, final totals etc. are all shown on [login to view URL] - this is fine. 2. Customer then clicks "Make Payment" - at this stage I want the customer to be taken to another URL but all the shopping basket information stored in the database (they can be transferred to a new database if it is easier). 3. Customer then enters payment information on this new URL (which will be on a secure server, https://etc. ) 4. Once customer submits the form on this new URL an email is then sent to site admin and a separate email to the customer. (Both emails will contain order information, the email to site admin will contain payment information - this will be sent to a secure email address but this just behaves like a normal email) No payment details are stored on the database. Please let me have your rough bid and time estimate. I will provide the exact full specification, current website URL and new website URL in further information once I have received your initial bid. **PLEASE NOTE: 1. I WILL NOT DEAL WITH ANY CODER WHO HAS A RATING AVERAGE BENEATH 8.5. 2. I WILL NOT DEAL WITH ANY CODER WHO HAS LESS THAN 5 RATINGS 3. I WILL NOT RESPOND TO ANY GENERIC BID YOUR BID MUST BE SPECIFIC TO THIS PROJECT I WILL NOT EVEN LOOK AT YOUR BID I WILL JUST DELETE IT SO PLEASE DO NOT WASTE YOUR TIME ON THIS PROJECT.**
