Andrew,
The old sage saying is "write what you know". That means understanding your own passions and writing about them.
My Godson is a ten year old with a passion for skateboarding, so I wrote a story about he and his buds going skateboarding into an area he was forbidden to go and getting into trouble with his bud's, but using his skateboards to go and find help (Police and ambulance) to rescue his buddies. Since they live in a great area to shoot (Prescott, AZ) and I have a good friend in the Sheriff's dept. the story became a slam dunk.
It's just hard getting his Dad (my best friend) to pay for the shoot. That's the tough part.
"Write what you know" and then develop it into a "cheap" shoot by using your imagination, and maybe some of your Uncle's money.
