This is a fuzzy number, dependent on a long list of variables. One is your marketability. Another is your client list. Still another is how much help (in house or with vendors and agents) you have for negotiating, editing, filing and delivering assignments. Finally, there is the complexity of reporting and research your jobs require. You also must realize that if you plan on selling prints and stock as part of your income mix, those efforts require time. Some say it takes two days of marketing, prep and mop up for every day of shooting. Others say figure on three days or more. If you shoot and deliver on deadline in one day, have regular clients, have many multi-day assignments, and always get paid on time, you can probably shoot more days than a rural photographer who may be needed by any given client only once every few years. Be realistic. For perspective, realize many photographers report 100 or fewer paid assignment days in an average year. That averages to two days or fewer per week. Running a business and shooting that often will keep most folks busy. Finding time for a life and moving at that pace or faster can be difficult or impossible.
