Hi puddy!
You will find all types of reseller plans for purchase from various hosts. There are some that offer one big chunk of space and then you are able to split your accounts up and sell as you see fit. You only pay the one price for your "bulk reseller" account.
We dont directly target resellers but our options are abit different than some. We require a "reseller account" to be purchased, and then you add your resold plans as you need them. You purchase these at a discounted rate and then mark up as you wish. Our system sends you the Welcome email, which you alter and send on to your client.
