"managed" vps reseller?

So I thought selling VPS needs some degree of knowledge in managing a server.
Now there are two types reseller they can choose to sell, that is getting a discount from providers and sell at discounted rates. Basically at the end of the day, one only gets a commission. As for resource reseller, one can expand in the future by colo its own on server or perhaps rent one. This "managed" includes all sorts of troubleshooting so resellers can move on in bad days. O.O Is there any provider providing such service? An untapped market? :O If one is to buy directly from dedicated server provider or a typical managed vps server, I am doubting if they are going to assist you at all? I mean, assume the reseller is newbie to vps
