SAML2.0 integration

I have a project to use SAML2.0 SSO. Need someone to create a package which can do following. A) Accept the SAML2.0 request from the client which include the user details. B) Validate the user with the client's system. C) Once validated, get user details from their system like name, email, etc. D) Process the information in our system and create some data and return a URL to access the data on our server. We are service provider. If someone can work with SalesFactor SAML2.0 system, that will be added advantage. Not a big project, but can lead to many upcoming opportunities.
