Hi,
After carefully reviewing the experience requirements of the job description, I feel that I am a suitable match for the job. I have excellent experience with VPN management on Ubuntu servers, their administration and optimization. I have been working with different webhosting companies as remote technical administrator, and I personally use Ubuntu VPN for my work.
Since you have already tried to setup VPN using tutorial for which you provided link, I can troubleshoot it and fix the error. I will also document and will provide you steps to install next time. If you wish, on some little more charges, I can also write up a script which you can simply run next time on Ubuntu server where you will want to install VPN.
The benefits of working with me are, I'm available on Skype and Telephone, and you will get a fast response from me on all your queries.
Thank you! I look forward to Hiring from you soon
Shahbaz :)
