Salesforce Consultant

Hi, We have a web app and you can login to the web app using Salesforce Authentication. We need help with integrating this web app into salesforce. We need to analyze it and see what would be the best way to launch it appexchange. It needs to be a tab in Salesforce and need to be able to install it from app exchange. You must have done similar Salesforce projects and also please send us relevant experiences so we can consider you for this project. Before we begin the project, you must sign a NDA.
