need a new host quick!!

[محروم.كوم]

ah nightmare - just recently moved across to vb4 from php. For the last 9 months our forum has been building up to a massive charity event (the largets of its type in the world) which climaxes this sunday.
Anyway we have been hosted on a sharde plan with 1000megs for about 2 years then suddenbly account suspended - took ages to find out why - apparently our forum was using upto 40% of the resources (their limit is 4% - I received no notifiaction as they had an old email address!!

So the only solution they have is to go from dhared hosting at $5 a month to their dedicated at $159 a month.
My site cannot afford this. We have 212 memebrs, vbulletin suite and a photopost gallery (around 200 photos) and that is it -can anyone suggest a host? also Im rather worried how such a small site can drain so much resource? we have a shoutbox and advanced stats running but thats iand even then as I said 212 members - most we have ever had on at one time is around 25!! we dont run an arcade or anything like that.
Im really miffed that this happened 2 days before a charity event so any help would be great
thanks
