Web Design Company starter kit

I am going to start up a web design business of my own out of my house at least for now, I have a partner in crime here but may be on my own for a little while at least, allready have a good lawyer and salesman both in the family.

I was wondering since I don’t have my own server space who would be the best to go with for initial hosting for my home page then down the road for clients own server space and all the additional things they may need.

Within the next few weeks I will purchase a domain name and server space and begin designing my own site, regardless of any additional help from my old partner so I need to know most of this info pretty quick.

I know Mosso seems to be one of the best picks if this thing becomes big but at $100 a month is pretty pricey for now. Any additional comments would be much appreciated.
