I just finished a simple (for me) job for a client. He knew what he needed but he did not have the software or knowledge on how to produce it. He showed me a sample of what someone else produced and was thrilled when I quoted a price.
In the end he wanted a PDF file that he can print on 8.5 x 11 inch paper on any common office color printer. It was of various areas with the property outlined and I had to figure out how many acres it was, the lat/lon of the corners of the property and some other details. I had to use 8 different software packages to produce the PDF in just the way he wanted it. It went real fast and our only cost besides the overhead of the office was one piece of bond paper for his copy of the invoice. It was kinda fun trying to figure out how to do the first one. The rest were a breeze. I felt guilty charging him that much but he was being raped by some other company. They took a week to do what I did in just a few minutes. He thinks I am a hero.
It is nice to have a quick easy very profitable task for a client and have him love the product.
