To make a decision on what to develop, you can do an analysis on your ideas. Come up with categories like Cost to Develop, Effort in Time, Who/How Many Will Benefit, Profit Potential, etc. Score each idea based on these categories, weight them according to your own priorities, and whatever floats to the top is the one you should focus on first. Getting one or two outside objective opinions might be a good idea to help keep your scoring honest.
