Review

The template is a free template which is one of the major downfalls of this website. The font doesn't look professional at all, maybe try changing the font to something like Verdana?

Should be changed to:

Our services have been revamped with an additional server, new billing and support software and better uptime!

mainly because:
HelluvaHost revamps our services

doesn't seem to make sense at all. Poor grammar.

Can be changed to:
Reseller Accounts are now Available at HelluvaHost! Exclusively, we also offer 4 different types of Live Support.

there is no need to capitalize all letters in a word, makes the company look unprofessional.

In my opinion it should be like this:
Welcome to OneReseller!

What separates OneReseller from the rest of our competitors is our extremely low prices. We are well-known for our outstanding customer support services and our amazingly valuable webhosting plans.

Why should you host with OneReseller?
Hosting has never been easier with One Reseller! You can get started with your very own website quicker than you imagined with our incredibly low prices and outstanding customer service.

Your Webhosting plans
Data Transfer should be changed to "Bandwidth". Most people wont understand what you mean by Data transfer.

In my opinion it should be like this, instead:

About Us

I think it should be:
About Us

Formerly known as HelluvaHost Incorporated, was started in 2002 when we could no longer tolerate the overpriced web hosting companies that charge extra fees for nearly everything, this led us to the decision to start our own webhosting company where everything anyone could ever need would be included for a one all-inclusive low price.

Titlebar
The titlebar in my opinion should be:

OneReseller - Private Label Reseller Plans

the .net is not needed..

Reseller Hosting Plans Section

This is good overall, nothing needs to be changed here.

Services Section

The arrows (>>) next to Extended Services and Webmaster Resources seem to be out of place and they really should be down next to the word not above it.

Customer Support Section

In my opinion you can change that to:
Live Support:

OR

Support via Instant Messaging:

Overall Suggestions
My main suggestions is to change the Font and get a new template.. well at least a template that doesn't look like its free.

Overall Rating

Please don't take offense, I try to be constructive in with my criticism.
