Adding functionalities to existing market Place

Hi there,

I already have an NFT marketplace portal that has the following functionalities:

- Ability to explorer NFT
- ability for the admin to upload Image/music/video
- Ability for the user to buy Image/music/video

however, I need to add the following functionality:

- Ability for the admin to mint NFT from backend by adding image/music/video and parameters) and add that to explorer.
- Ability for user to buy the NFT
- Ability of the system to send the NFT link via email when purchase. The link will be a QR code and it will have the address in BSCscan.

Thanks
Fed
