InMotion is forcing me to upgrade...help

[357Magnum]

Basically InMotion is forcing me to upgrade from a Business level server to a virtual dedicated because they say my site is hogging resources. 28% of an 8 processor machine they say. This wouldnt be a big deal to me if the price difference wasn't nearly $900 over the year.

So here it is, any help or suggestions would be appreciated.

Ok so I was running this same site over on StartLogic for the last year and a half...but the site kept crashing and SL tech support sucks....so I moved the entire site to InMotion's business hosting package...the specs can be seen here

I got the power plan. http://www.inmotionhosting.com/hostingplans.html

Now, some specs on the site

vb 3.7
Members = 750
Active = 300
Average throughout the day logged in and posting = 30

They are saying that the site itself is taking 18% server load to run...and that search.php is taking an additional 10%

I know pretty much everyone on any type of community site uses New Posts like crazy...I had the time between search set at 20 seconds...then changed it to a minute when I got an email last night about it...but then they turned the site off and threatened to keep it off if I didn't disable the search feature immediately. I have 8 admins/supermods that the limit is disabled for...which I don't think I can change anywhere...but only 2-3 are usually on at any given time.

Does any of this seem right???? I have been on sites that were 1000x bigger than mine that shit if I have to spend $1000 per year to host mine they must be spending $10k+ Are there any optimization things I should check or change?

Again, any help would be really.....well....helpful.

Thanks!
