Looking for eCommerce solution to attach to NextCloud platform


We are currently look for a developer for create a payment solution to plug into Nextcloud platform. The users must be able to signup or login to an account. Which will then take them to a paying subscription page, where one can select the type of service they are interested in, and pay via Visa, Mastercard or Paypal then an account will be created and after a successful transaction the account is created and access given to the user.

Within in the same solution the admin must be notified when the subscription is expired, so the account status is disabled until another subscription is purchased.

I am new to this forum so any assistance would be greatly appreciated.
