If you are a web designer looking for the best hosting option then I would definitely recommend a reseller plan like http://www.pickaweb.co.uk/reseller-hosting.htm
This way you can earn extra revenue from web hosting in addition to your web design services.
Your customers get their own control panel (CPanel) and this way they don’t need to trouble you to make changes to email passwords, create email accounts, etc.. You need to offer your customers first line support though & if there are any issues you can’t resolve then we are here to support you.
