Ok i am assuming thats dollars...
I think you would be best on a semi dedicated like what im on atm..
As long as you dont use VBShout then the resources shouldnt be an issue
I use vbshout but for my staff only....
The reson a i am saying semi dedicated is to save you upgrading again in the future, if you can afford it then do it!! with westhost its a virtual server with is better than a shared server, theres less sites sharing for 1 and 2 you get a lot more resources......Have you had a browse, what do you think?
heres a few more to look at...keep ya options open
