First, I'm a fairly green on this subject. So, go easy.

I do web design and development and would like to set up a way to be the central host so to speak for my clients. Currently they are scattered across multiple hosting companies. I've looked at some the cheapy options like a LunarPages and some of the more robust options like RackSpace Cloud and Linode. RackSpace has a reseller program, but it's managed and more at the top end on cost. I'm not seeing any type of reseller program in place for Linode.

Can I purchase a higher Linode plan and use Apache2's VirtualHost configuration to handle multiple domains (about 8 domains, but hopefully will grow.). Or, am I not thinking about this correctly?
