I NEED A WEBSITE PROGRAMMER TO MODIFY MY PHP WEBSITE

Hello! I need a professional front and back-end website developer. I need some modifications on my website

 what do I need to be done?

1. I want when users signup they should receive a verifying link through their email to confirm their email.
 

2. I want to add payment gateway integration to my website where users subscribe to monthly payments. I’ve already had the program made on my admin panel, just have to add the payment gateway and modify it
 

3. I want to modify my email template design. The one I’m using now doesn’t have a template design.

These are the major thing I want to modify on my website. you must be a professional programmer, especially in PHP becoz my website was programmed in PHP.
