Linux Admin 10 Years, WHM / Cpanel Expert. I can install your ssl for you with no problem. The time it will take to install will depend on how long the SSL company you choose generates the ssl.
This does not include configuring the website(s) to use the ssl. If this needs to be done it would need to be a separate project.
I install SSL's all the time for my hosting clients and can do it with ease.
Thanks for your time and consideration,
Shawn
