Graphic Design

I'M beginning to see the pains of having client's as a Freelance Graphics Designer. I'm creating these brochures and ads for the local school mostly as a favor. I didn't have them sign any of the normal Freelance contracts or agree on any stipulations before taking the job. I saw the previous brochures/ads and knew I could create something better in my sleep. Unfortunately, I think they are under the impression that they actually have me contracted professionally for my design skills. I'm under no obligations in my opinion to give them the "perfect" design they are looking for. I've already exceeded the previous work. yet they have turned down my first designs and are asking for more. When I give them a look that says they are a bit nuts for asking for something else, they bring up that they'll "find some money to pay me" for the work i'm doing. A vague promise isn't the same as having it in writing. really, its not so much about the pay, even though these jobs should cost them hundreds of dollars a piece. nope. its more about getting my name out among the locals of what skills I bring to the island. it's just irritating that i'm expected to put a lot of time and effort into a job i'm doing almost pro bono since its for the education system that employees my wife. if it was a shit design like this one i fooled around with:












Then feel free to tell me to try something else. BUT when its a decent design like in the previous post or this one here:




or this:

then please. just thank the nice man for his work and move on.
