Dear Concern,
I checked your requirement to integrate payment api for credit card processing. And I can help you to do so.
I can integrate Paypal payment API which allows MASTER VISA DISCOVER, AMERICAN EXPRESS.
I'm a senior software developer for more than 5 years. I have expertise in PHP, MYSQL, HTML, CSS, JAVASCRIPT, JQUERY, AJAX, ORACLE, JAVA. I can show you my paypal integration expertise.
I believe in quality work with minimum price. I'm confident to do the work. I'm looking forward to you to hear from you.
Best Regards
