You may want to "Google" air taxi's or air taxi service or something to that effect. Also, you talk about how general aviation airport affect the local ecomomy.
Suggestion:
Whatever town you live in, go to your local Dept of Arpts or the Planning Dept of the government seat that runs the airport(s) in the city or county/parish were you live. Ask for a complimentary copy of the Airport Master Plan. Within this plan, you will find information on Land Use; Economic Impact on the city or county; Airport Operations and Management Study including potential Air Carrier Ldn 65 Noise Contours; Clear Zones; ALP's - (Airport Layout Plans = runway & taxiway configurations); Noise Abatement; and really a ton of other information I think that would really set you apart from the other students.
Hope this helps. PM me if you're able.
