Ktools photostore photo's offsite storage(AWS) and transfer code and database back to old server

I use Ktools photostore to sell photo’s from shoots. They stopped the support, but they were so nice to provide the full code without encryption. Ktools photostore is build on core php Store photo’s offsite is supported by default Currently it is hosted on Amazon server, for the last year. Before it was hosted on a local server by [login to view URL] I still have that hosting location. Antagonist ordered me store the photo's on a service like Amazon S3. So we moved every thing, because it was the quickest option at that moment and because the site was not ready for off site storage. But we really want to move the site back with the photo's we sell stored ofsite on amazon. Just for stability. The current solution is not stable especialy with sending mails from the site like contactforms and order confermations. Short list what to do: - transfer Site code and database back to antagonist server - photo’s to sell on Amazon - Check security and update where necesary. - cache and photo’s must be protected - undo reroute from url’s from amazone server back to antogonist server Requirements: No downtime Code will be on hosted on antagonist, photo's to sell on Amazon. Must be done with in 7 days Only respond if you can work on this solution for the price you offer no extra payments
