Build Active Directory Password Self-Service Solution

Hello, I am looking for a visual basic (VB.net or C#) expert to develop an Active directory (AD) password Self-service solution. This solution should help domain users perform self-service password reset and account unlock based on authentication factors. The application will have two main interfaces. The first one will be a web interface and the second an interface on Windows Login (modified GINA dll). These are the factors of authentications we need: - Questions - Smartcards - USB (ex: Yubikey) - Time based one-time password (ex: Google Authenticator, Microsoft Authenticator) - Email Most of them have available APIs on the Internet ready for the implementation. The software should also be able to simply deploy the modified GINA client and/or agent remotely within the domain. It is crucial for the users whether regular users or administrators to have a great and simple UX. Everything should be simple, unlike other solutions on the markets such as ManageEngine’s ADSelfService Plus, Thycotic’s Password-reset-server, and others which resemble what I would want. It would be better to work with an experienced enterprise or a group of experts to ensure quality and efficiency. Also, we would optionally need someone who can help us document the software or explain it with videos and/or other support. I need you to provide me an approximation of the project timeline, budget, and other details with a detailed explanation of what you will provide me. I have also many other solutions to develop. Thus, I am looking for a long-term partnership. Thanks,
