3 New Web Pages and Google Hosting For 2 Years Old Java, J2EE, JSP, Spring JDBC Web App

If you are new to Google Apps engine, it is still ok. Just let me know what is best you can do. I am reviving a JEE / Java 6 JDK / Spring Jdbc, JSP project after a long time (after 2 or 3 years). I had some important things came my way and got busy. I need some one who can take the existing source code from my SVN and put it on the Google Hosting (with I guess Java 7). Although I have just created an account with Google App engine but prefer if you create your own account and then do the needful. Provide me complete documentation with screen shots and brief videos. So that I should be able to repeat the complete process from my laptop computer to host it on my google account. The documentation should be complete and explain every thing that I need to do to set up environment on my local laptop / computer and after running it & testing it on local computer to deploy and run it on Google Hosting. I like to know, if I want to run 2 or 3 different versions of same web application at the same time, then how to do that. I will also provide you the Domain Names (previously purchased) so that the web apps can be easily accessible via domain names. This web application will actually be accessed by a PHP web front end. The customers will subscribe to a WordPress or Joomla / Drupal web site. After the user is authenticated they will click on a link. So that PHP website will then forward the user to this JEE web application. For the time being it is ok for the user to re-log in this web application. After the above work, I will provide info about the 3 new web pages. After accepting your bid, I will provide you access to source code and existing documentation with images and WIKI pages on how to compile & deploy. As part of this project I am expecting you to resolve minor bugs / issues and compatibility problems if any. To my understanding as of last 2 / 3 years ago the source code in Trunk of SVN was compiling and running fine. So I do not hope or expect some known issues.
