With respect to your question... AuthNet, CyberCash and Payflow Pro are all just payment gatways - NOT actually payment processors or merchant acquirers.
In other words, they are such point-of-sale services that -attach- to an existing merchant account setup with an acquiring bank.
The rest of the items on your list are actually third party processors and thus probably a better comparison for what you are trying to put together.
One suggestion for you - be very, very careful in the planning of this new service. There is a lot of risk involved in it and most banks will not approve that kind of an account. And the ones that do, will likely require reserves and strong financials.
