Sorry to see you haven't had any answers to date. Maybe mine will provoke thoughtful answers from others. I'll get started by saying that I've been in your boat. "Never been done before" and "radical new approach" create excitement for entrepreneurs but fear (e.g. "I'm not touching that!") for some investors. Nevertheless, my opinion (with little to go by) is to not let that stop you. Present your new concept in all its glory. Develop a powerful overview which will generate a big "WOW" from investors. Include practical examples that bring the concept to life from a client's perspective. Describe total start-up costs, delivery costs, customer benefits and a phased implementation to minimize the upfront investment. Your phased implementation plan will reduce the fear you created when you described the concept and the total investment required before the business generates cash. Example: Phase I: Convert the concept into a service and define a sales pitch approved by an advisory group. Phase II: Prove a key component on a small scale or limited scope test. Incorporate standard controls in your test design so investors trust the test results vs. existing methods. Phase III: Expand the test with additional components, an expanded scope and/or an additional client. Each phase should conclude with additional investment for the next phase. Whether there are 3, 4 or 5 phases in the schedule depend on what you have to prove before roll-out. Positive results after each phase will build investor confidence and gradually improve your chances for long term success. I would be happy to help you create the plan and overview.
