Greetings neighbor (from Utah, USA). If you select solely on dollars per hour, be prepared to get what you pay for. In my opinion, you must find a freelancer who gets to know you, and your various skillsets fairly intimately, in order to construct actionable bids here on Freelancer.
I have never done anything like you are asking, but when I seen Project Management among your list of competencies, you caught my heart. I am a certified Project Management Professional. Anyway, I wish you great success in your endeavors here on freelancer.
