It's all quality based and the system is only as strong as the weakest link in the chain.
If I do not choose a high quality datacenter I cannot provide a high quality product. As a reseller, if you don't choose a high quality host who has chosen a high quality data center, then you will not be able to provide a high quality product.
A reseller is only as good as the host they choose.

Hello,

Sorry, I am a little late into this post. I was working on providing quality support to customers. Which leads me to say that no matter how cool your billing system, how sweet your support system is, and how great of uptime you have. You will be the key to the success of your web hosting company.

You might have to work 80 hours a week. You might lose sleep at night and you might be on the phone through your lunch break at preschool (I know, I am on my snack break right now ) but if you cannot provide technical support or higher someone to do it for you you might as well not even start.

Make sure you have the time to be able to work the long hours. After over a year I am still working all the hours. I enjoy it but somedays are just to long.

Try a reseller maybe a nice VPS. Slap a client exec license on there and maybe a support trio or maybe just an e-mail account. And, if you are ready to do it go for it. If not read some, listen to some veterians in the industry. Maybe, even some "kiddie" host like me. (I do not know am I still considered a kidde host?) and you'll do just fine.
