This question is mainly for those who do portrait photography full time, although any help would be much appreciated. I have been considering going pro as a portrait photographer for some time. Without going into too much detail; I would be working on location (clients house or place of their choosing), essentially the studio would be brought to them. My problem is that I really have no idea if there is a market for it. Looking on the internet, in local ads and telephone directories hasnt led me to any photographers doing what I want to do. I have done a business plan and outlined different marketing channels but have absoloutly no way of assesing whether or not they will be succesful, mainly because I have no point of comparison and no idea who would want to have their portrait taken. Ideas?? Thanks.
