Hello,
I understand your project goal and confident I can complete your project in a timely manner provided you have root access to the VPS server that you need this installed on and a cPanel account for the WHMCS installation.
I am very active, detailed oriented and can communicate frequently while on your project as needed. As my current role at a major web-hosting company I am more then experienced enough to complete this project for you without issue.
Please let me know if you have any additional questions and look forward to hearing from you.
