Promoting Your Film
One thing I have learned from friends who have made independent films is that you have to start promoting your film the minute it is complete... as a matter of fact, don't wait, as soon as you have a title run with it. This is your baby, your little brain-child so get out there and promote. Large studios have their own publicity departments but the little guy or gal has nothing but their reputation by word of mouth. In order to build that rep you have to work at it and there are various tools that you have available to you.
Finding a Location or Your Film
Being a location scout would seem to be the most fun out of all the jobs offered in the filmmaking industry. It seems that it would be a dream vacation to travel and see if a location checks out or not. Believe it or not, headaches abound in securing a location to shoot.
Fly Filmmaking is closely related to Guerilla Filmmaking. The latter is done literally with all that there is on hand and in the shortest amount of time possible. Spike Lee did this with his film "She's Gotta Have it" and he has received continuing critical acclaim for his first effort.
