I run a web hosting service(VPS/CentOS/Cpanel) and have been in IT for 15 years, so I have the technical knowledge and experience to solve pretty much any issue.
I do not have direct OVH experience, but I'm certain I can get you up and running, as long as your IP has already been assigned and only needs to be configured in your server.
This is the second time I see this job go up, so I figured you were having trouble finding someone competent. I'll help you.
