Managed Wordpress Hosting, Where can I order it?

[Chemicals]

I looked at managed WP hosting, thinking a 'cloud' option may let the site grow to 500 members or so & weather traffic spikes - and then I can move it to something more permanent. So I'm really not sure which way to go - and perhaps it's because I don't understand hosting that well. A distributed grid sounds cool, but does it work in practice? Is eventually getting a dedicated server unavoidable? What the hell do sites that have a lot of members and traffic do?

What can you say about Hostingsource.com and Hostnamaste.com web hosting?
All advice will be appreciated - I'm planning on launching my site, I need to get this squared away ASAP. Thanks!
