Im just wondering exactly what you have to do to start up a webhosting biz. how much does it cost. where do I buy servers? how large is the profit margin? I just wanna know as much as u guys can tell me ;)

I would suggest you do a search HERE (http://www.webhostingtalk.com/search.php?s=&action=showresults&searchid=538750&sortby=lastpost&sortorder=descending) it has been covered many times.
