Help with Google SSO SAML in ColdFusion/Lucee

We are looking to provide single sign on (SSO) to our online learning website. Alongside our existing login we wish to add the ability for our users to login and sign up using a google login, Microsoft login and also potentially single sign on from RMunify. Our existing website is written in ColdFusion (Lucee) and we would therefore want the SSO to also be written in ColdFusion and connect to our existing login and user database. We are happy to discuss further and we would encourage you to do so in order to get a closer idea of our needs. We would suggest a period to scope the project in which we would pay an hourly rate but can then agree a price for the project.
