Hi,
I am Web developer with 10 years experience. I can provide customized integration with different payment gateways for your website. For instance, I made such an integration with http://www.cerberusweb.com.
Is it a full list of functionality to be added?
Send me your comments how you see the final result (with full list of features and design), so that we can estimate the cost and turnaround time.
Except Payment Gateway Integration, I make custom modules and plugins, various web-applications using PHP, HTML5, CSS3, JavaScript, jQuery.
Ready to start now. I guarantee high quality work, quick answers and responsibility.
Best regards, Alex.
