Hello,
I am a reseller for a company, and just stared doing this about three months ago. In that short time, we have grown at a pretty decent rate.
Now, the company we resold for is going downhill in service, and we are looking to start with our own servers.
However, we don't know how to run one.
Is there a place I can learn this? Or is someone willing to help..?

Thanks!

Try Burst.net they seem have a good reseller option. You can even have an 800 number, an ananymous support center handled by them for you.

If you are running on Unix OS, get Unix Unleashed. If you are running Linux OS, get Linux Unleashed :) These are the 2 books which i always recommend my friends and clients when they need it.

Or if you want, you might want to hire part time system admin to do these tough job for you.
