Dolphin and Magento registration integrate

Looking to integrate at registration level - Dolphin and Magento.

Ideally, people register via Dolphin, which automatically registers them into Magento also. Same for logging in and out.

Using Magento Community version.

Dolphin latest.

Magento pages will then be displayed within Dolphin via iframes so shouldn't need further integration.

Open to discussion if anyone can assist with this, budget depending on timeframe etc...
