I posted this in the webhosting section already, but was advised to bring it over here as well for more specialized answers so here goes.
I came here a little over a year ago looking for a web host for my vBulletin forum based website and was directed to A Small Orange.
They were a great host to me for a year and I want to thank the people here that recommended them, but apparently the site is now too large for their shared package and I'm back looking for new recommendations.
Currently use about 2gigs of HD space
Roughly 8 million hits a month, as high as 15
50gigs bandwidth/month, as high as 120
400-800 total users in a day
Up to 2000 posts per day
A Small Orange is pointing us to their Professional VPS plan which runs $90/month for 256mb ram and 500mhz CPU and plenty of HD and bandwidth.
As a worst case scenario we'll do that, but as a non profit (no income at all actually) that number is a bit high for us.
Can you please recommend any other stable hosts that could handle our needs?
Edit: Also I lack the techinical knowledge to setup a VPS so I would need a host that takes care of that side of things for me.
Those are the top 3 I would go with. Steadfast and LiquidWeb are managed, so I believe they setup and maintain the core OS (IE: updates to cpanel, OS updates, etc). PowerVPS is also managed I believe, but I do not know what level of managment they provide.
You should fire emails to as many companies as you find, and see which ones have the best response times, etc.
I don't know what control panel A Small Orange provides, but Cpanel will be your best bet. It is easy to learn and has alot of documentation available.
Finally, check around these forums for deals on VPS's. LiquidWeb currently has a $10 off deal and I believe Steadfast and PowerVPS have run some in the past.
Good luck, and post here if you need anything else,
