Hi,
I have read your details that you need a PHP expert who can build the PHP script for including certain features so provide me details of access info so that I can help in. I will provide you website in wordpress which will be easy to manage by yourself with great SEO experience as I have experience team in core PHP and Wordpress CMS with PSD to WordPress, customization of WordPress core, development of custom plugins and adding payment method with backend PHP and mysql database.
Looking forward to hear from you soon.
Regards
Kaushal S
