Thanks @LeonidS.

I would be looking to separate/hide each individual from one another, not just the user levels.

@Tim I found a opensource CRM called SuiteCRM that seems to fulfill the backend function I am looking for, but still requires a front facing website, form collection method... depending on your purpose, you may be able to join forces between your UNA site and using that kind of CRM. Unlimited users with that one, which is a rare find so far.
