I need a very very good PHP programmer to work with me in creating a payment gateway for a series of websites. They will all use the same gateway, but will take on the look and feel of the originating site.
Background: We have 6 different websites concentrating on one different product each. Each website currently has its links to a payment processor (Worldpay/Sagepay/etc) and has separate account details to all the other sites, even though all sites are owned by one company. We want to rationalise this, by creating a payment site, with only one account with the payment processor (plus the option of paying through Paypal/googlepay) so that more microsites can be added easily. If a buyer comes from say site A, then the payment page must look like site A - so similar headers, colours etc. Cookies should be used so that traffic can be tracked, and above all, we need the sales to track via a snippet of code placed at the payment processor's site.
There will be a limited amount of graphic work to be done too - to get the look and feel elements from the other sites, but if you are not able to do this please indicate this on your quote.
Any questions - please holler.
Also - if you have any sites you have done that are RELEVANT to this project please list them - anyone who lists a load of IRRELEVANT sites will be disregarded from the start - as I know you won't have read this far!
