Thanks and good luck ## Deliverables [login to view URL] Payment System I need a coder that is experienced with [login to view URL] to setup a payment system on my website. It needs to do the following. Create form on my main website page. This form will collect all the customers shipping info but not their credit card info.. after they click submit the customer will be re-directed to page 2. Page 2 will have a payment form with the info they already filled out automatically filed in and it will ask for their credit card info. also there needs to be a box that can be clicked if the customer needs to ad a their billing address if it is different than their shipping address. after they click submit they will go to page 3. On page 3 they will be asked if they want a upgrade and buy more stuff. I need it to be setup where all the customer has to do is click on a buy button and their credit card will be charged without them having to fill in any more info. I want to have up to 6 pages like this were the customer can just click 1 button and order again without re entering their payment info. If they get a decline on any of these than I want the system to allow them to fill in their credit card and billing info again. this way they can use a different credit card. it will also automatically fill in their billing info but have a button that will clear it if they need to enter a different billing address. Also this needs to be setup for recurring billing. My first product is a free trial (they pay shipping) for diet pills. after the customer pays they will be asked to upgrade and buy a 6 month supply. if they order this their membership must automatically be canceled. Some of the up sells may be monthly recurring products as well so they will need to be setup that way. I would like this built so there is a config page or whatever you want to call it that allows me to change the amounts and names of each product. This is as easy as a php page that I just change the numbers and names of products and upload myself. If you have any questions please ask me before bidding. Please do not bid if you are not certain you can do this job on time and exactly how I want it. Also please show me payment systems that you have setup so I can make sure you have done similar jobs in the past. Thanks for taking a look and good luck with your bid.
