Video/Whiteboard explainer videos

We're a small startup consulting firm in the Healthcare space. Our target clients are Health-Systems, Health IT firms and larger consulting firms. We need three, or possibly more explainer videos for each service line, as follows: 1) Hospital Pharmacy interim staffing and management 2) Health-System care variation reduction and profitability consulting 3) Services for Health IT firms, digital health application developers and startups, and 4) Confidential and discreet project staff augmentation services for larger consulting firms. That's the grand plan. However, initially, we're going to start small and create one general introductory explainer video. Projected Timeline and Milestones for this project: 1) Advise on content for video 2) Create script 2) Create visuals 3) Up to three iterations 3) Unlimited minor tweaks (don't worry, I'm picky but reasonable in my edit requests) 4) Turnaround time should be 15 days, with content decisions made by day 4 and the first video draft available on day 7. 5) If there's anything I've forgotten, or if you have additional recommendations, please let me know. Thanks.
