to EUK Forums!
If you see on the main page of EUK's website, you can see the link to Business Web Hosting packages they offer! They offer 100% Network and Power Uptime Guarantee on those plans. You can find these plans
here.
I am not sure if EUK allows to resell the above plans, however, if you want to be a reseller then considering Reseller Hosting plans will be best solution to start with.
They are best of all in the hosting industry. They believe in customer satisfaction, hence, you will definitely get quality support from EUK guys.
