I run a website that gets about 7000 visitors a day and 50,000 page hits a day.
I can recommend to you 1and1 hosting services. I have a quad core server with 4 gb's of ddr2 ram and I rent it all for $79/month flat. I currently upgraded from a dual core 2 gb machine which costed me $59/month.
They use plesk panels and you can image the server to whatever control panel they offer, which I think is pretty neat (at a click of a button). Through my 1 year hosting with them, I can say its been a great experience so far. They have 24 hour technicians you can call directly if you ever have server issues, and in 1 year my server has been down for 2 hours (due to some faulty crossover they messed up on) but in a year, that's pretty good. The rest of the time my server's been online and kicking!
Customizing the server through Plesk's Control panel has been a joy, very easy to do. I am a web developer and I do set up many dedicated servers for all sorts of tasks at the company I work at, but managing my dedicated server's with 1and1 has been a breeze.
Hope some of my advice and experience helps you there. Cheers!
