Winforms application with Clickonce deploy manifest sign

Post Client Info Here

I have Winforms application, repository located in VS online.
1. When i build it i am getting errors related to manifest and signing. I need somebody to implement a solution that works for multiple developers working on this repository.
2. Build script should publish the software
3. Upload published software to Amazon S3. probably some custom script required here.

You must be familiar with these tasks before bidding. Please dont bid just because you know how to create clickonce application, my requirements involve VS Online, build scripts, manifest, code signing also.
