Hello
I have gone through your project description carefully. I am a 5+ years of professional experienced developer who provides surprisingly quality.
You want to remove these things from your existing website double e-mail fields from registration form, check box and copy apply to become a vendor on registration form and more.
I will fix these all issues of your website and i will fix temporary password issue, and will remove vendor/customers to administration, paypal payment gateway from your existing website.
I am expert in PHP, HTML5, CSS3, Bootstarp, Wordpress, Javascript , Magento, payment gateway integration, API integration, Plugins integration/optimization and more.
I am willing to start your project now from this time.
I would like to discuss more about the project requirements so initiate the message board where we can mutually discuss about the project.
