With any VPS you should be able to resell webhosting, just make sure you have some decent spec's if you plan to use cPanel or similar. As for the unmetered BW and a la carte upgrades most will be able to provide that to you, just ask the pre-sales before you commit.
ok because most of the ones I've been looking at don't have unmetered, I was planning on using my own setup for panel and a the moment I just need enough specs to get off the ground, I figure that is something that can be bought "a la carte"
Try contacting the sales dept about the unmetered BW... While I can understand most may not have this listed on the site, I should not be something out of the question to implement for a potential customer.
