Build web-site with Social Network integration (LinkedIn, Facebook, etc.) in java - must include backend delivery

I need a fairly exhaustive website to be produced. Here are some detailed functionality in it: - Authentication. - Social network integration (LinkedIn, Facebook, Instagram, etc.). - AWS deployment: it is unclear the reception of the site, so I need t cover my ass in prevision of a good reception. I need an AWS deployment that will allow me to create new instances or change the nature of the instance based on traffic. The solution may include a load-balancer in front of the web-server component. - Must be written in java (could be Spring MVC or Grails or GWT). I am flexible which flavour of java, but java is important (since our business is java based). - EMail exchanges are apart of the web-flow. - E-commerce functionality is also part of the web-flow. - Custom widgets will also be needed in order to build survey interfaces (may look like [login to view URL]). - An administration area that allows to build custom surveys per industry and manage the different database values and reports on hits, sales and all. Deliverables: - Functional website. - JUnit with at least 50% line-coverage functionality. - Documentation (which class holds the logic for which area of the website). - Source code. - Deployment scripts for AWS instance creation. Milestones: 1) We deliver a complete definition of our intended flow to you (partial sample is provided, and complete sample will become available upon getting a signed NDA). 2) We agree on the technology to be used (Spring, Grails or GWT). 3) We agree on a deployment architecture (load-balancer or not). --- Partial payment here: 5% ---- 4) You produce the website. a) Authentication logic b) Home-page c) Registration page --- Partial payment here: 15% --- d) Status page e) Social network integration f) e-commerce logic: Paypal, visa, mastercard, etc. --- Partial payment here: 15% --- g) Custom widgets for building surveys h) Survey pages (defining and filling) --- Partial payment here: 20% --- i) Administration area j) JUnit k) Deployment scripts --- Partial payment here: 20% --- l) UT/IT passed m) Documentation deliver n) Integration of new design performed (material will be provided by us at that time) --- Final payment made ---
