Mailroom PO BOX web service

I am looking to hire a freelancer to create a mailroom PO BOX web service that has a virtual address and can be accessed by multiple users, as well as offering features like drop off/pick up and mail forwarding. This PO BOX web service should provide exceptional convenience and security for my personal and professional needs. The service should also allow easy access for all registered users so multiple parties can access the same PO Box without requiring me to share my passwords or log-in credentials. Furthermore, I hope to be able to have a reliable mail forwarding service provider and be able to customize the terms and conditions of mail forwarding if needed. I am also looking for a highly secure platform that provides encryption and other data protection measures. If you have experience in creating similar services and can provide a reliable and secure platform while meeting my requirements, I would love to hear your proposal.
