I have been running 8 web sites for about 7 years. 2 of those web sites are getting popular and I'm adding lots of information, consequently the sites are getting very slow at times and I'm running out of space. Someone suggest me to get a dedicated server, but I never deal with the server I just pay the hosting company and they took care of everything.

If I move to a dedicated server do I have to do all the configurations, install software, etc?

Can I have all my sites in the same server?

Should I move to a dedicated server with the following stats?

1 site = 5K visitors/day 30K pages. I need 10GB. Vbulletin
2 site = 3K visitors/day 25K pages. 9GB. Vbulletin
3-8 sites = 1K visitors/day 15K pages. 12GB. 1 with Vbulletin

Currently I'm paying around $100 for hosting all sites.
