Hi there, I understand you want to make an Education coaching website where you can sell courses online, conduct quiz, issue certificates and much more. I can do this perfectly.
I would be making use of Eduma education theme for this project. I would install, activate and customize this theme to suite the requirements for the website. I would also install plugins (LearnPress, WooCommerce, Mailchimp, BuddyPress, Thim Portfolio, Google Analytics, Yoast SEO and lots more) which would enable various functions like the curriculum, payment integration, conduct examinations, teacher registration as well as making your website fully optimized for google search engines with fast loading speed and many more functions. I would teach you how to manage this website afterwards with 3 months of support at no extra charge.
I would be hoping to hear from you. Please feel free to message me about the project. Thank you.
