Sir,
I recently left my position as a sysadmin at a well know hosting company (french).
I had my fair share of VPNs, webservers, mailserver, and so on.
I graduated in IT 4 years ago and been freelancing and working for companies.
I have over 9 years of experience with Linux as it's been my passion, as well as security, for years.
I own an EC2 server and a S3 for backups and storage in the cloud - hence why I will be able to help you out on this.
Please check my profile, previous works and reviews - people were always pleased.
Regards,
PS: Please get in touch quick as I'm starting a job as sysadmin in a few days.
