I have the basis of a story but I am unsure how to start. Not the actual plot, just the opening of the story. It starts with a meeting in a dive bar between a criminal/mercenary and an employer wishing to hire his services. But what I'm struggling with is how to set the scene. Do I start with a description of the area/weather first, or the mercenary who is my protagonist? Do I start with a bang or build from humble beginnings? Will too much description turn the reader off before they've been gripped or is this necessary to establish the scene? Is there something I'm missing in my start that I haven't accounted for?
