Hi there.
I would like to see your website to ensure the scope of the work, however, I can integrate WhatsApp chat support in your website and which payment gateway you would like to integrate as UAE have some limitations on it? I want to discuss complete details with you to understand your requirements, I am available now you can drop me a message so I can share my thoughts/expertise on your project.
I am highly interested in working with you and I am looking forward to working with you on fair prices.
Best Regards,
Jordan
