Do you mean you need dedicated server "to resell web hosting" or to "resell dedicated servers". I think that for $70 per month you can get P4 machine or a low-end AMD server. I would suggest you to research for so called "bargain basement" deals. Those are vacant machines that companies have in stock when change hardware.
Oh yeah, maybe you mean that you will resell hosting space... well, search the Offers Section. Will it be Managed or Unmanaged? But I doubt you will get Managed at that price, I suggest you add a bit more...
Just keep in mind reseller programs offer more than a discount on price, which is important, but price is not everything. I think you will find a reseller program to meet your needs, but you may need to speak with a company representative to work out the details, as the 1TB of bandwidth may be the one thing that makes the price not come at your desired rate. But if you're talking volume, I'm sure you can work out something.
Start as suggested with the offers here on WHT and then make a point to communicate through chat, phone or email with the hosts you're interested in to work out the details.
