Creating A Hosting Company

Hello, I am thinking about starting a hosting company. And was wondering about your opinions! The information is below.

[INSET NAME HERE]
Using SpaceCP when it comes out

[RANK 1 SERVER]
512MB - 10 Players
$3.75/month

[RANK 2 SERVER]
1GB - 15 Players
$7.50/month

[RANK 3 SERVER]
2GB - 35 Players
$15.00/month

And So On...
Starting out with servers located in the UK, then eventually in US and NL.
What do you guys look for in a hosting company?
Why do you choose that hosting company?
