Application Authentication, Authorization and Payment Server

We have a functional, working production environment that is used for application and extension licensing, authentication (oAuth) using the node module passport.js. Our system also handles payment gateways for 2checkout, Google checkout and Paypal. it functions perfectly for what I need for my own applications. Now I want to offer a package to other application developers that do not have the skills or resources to write their own sub systems for these purposes. We will offer this system to application developers as a SaaS solution. We need someone who can take this project to the next level, by building us a system that allows a user to create an account and sign up for our services. The system should automate and when account is funded and created, spin up an amazon EC2 instance to run the users app gateway service. The user would then configure their instance and take the information from our servers and incorporate that into their applications or extensions for use. Complete details will be provided to the winning bidder(s) I do not have a specification finalized, but there is a considerable amount of integration and enhancements to our existing server code that will be needed. IE reports, back end administration etc. 140 hours is our rough estimate from the Principal Architect. Bid accordingly.
