Thanks for the response.
I was thinking about revecom for my merchant account and possibly ubersmith for billing. I know the first server will be hard to fill, but I wasn't counting on filling it right away! I configured a linux server at rackspace with two 30gig hard drives, one for backup and it was about 300 dollars a month, what I wanted to spend. I don't like the Plesk v.2 control panel, thats why I'm getting WHM and CPanel, too bad its so expensive.
What do you think about ubersmith? Are there any other programs that do this type of thing, but slightly cheaper?
Where are the best places to advertise with the best results? Directorys, search engines, etc?
