I run a teaching academy. In response to coronavirus, I need to offer more online courses. So, I need to improve my website. Current Website has a few known issues such as 1- Admin Login Page cannot be accessed 2- 'Apply for course' form is not working there are some PHP errors also.
I need someone who could fix current issues and also add following new functionalities: Ability to Upload/Download Documents, Pictures and Videos Online Assessments / Exams (MCQs) e-Commerce (Payment using PayPal and Credit / Debit Card) Live Chat Functionality Data Export and Analysis of Enquiries Search Engine optimization
Please provide price for above functionalities individually also.
Please also advise the required delivery time clearly.
Looking forward to Freelancers who have significant experience in Wordpress and deliver the required features quickly.
