AWS and Infrastructure (e-mail, domain redirection etc) Support for Brazilian website

Hi, I need someone who will give me continuous support on my site's infrastructure, including: - Optimize AWS server configurations (cost x performance) - Implement/ manage automatic backup procedures - Adjust e-mail configurations (I run Google Apps, but some of my emails are being marked as Spam) - Redirect some recently purchased domains to my site - ... This will be an on going job and I plan to keep this person as our infrastructure support.
