There are a couple of camera groups in here and I have seen ads from photographers. For security, it would depend on whether you wanted photos touched up or raw. If you didn't care about touching up, then I would make arrangements for the photographer to use my own SD card, and he/she would be leaving it with me, so my photos would not be leaving the house. Experience differs, some preferring a female photog, and some preferring male. Everything depends on your comfort level, and how professional the photographer is, and whether they are also invited to play - these things need to be talked about beforehand. Also things that need to be talked about are price, what you expect to happen, and whether what you want done is even possible. Sometimes it's all about lighting and how flexible you are and comfortable you woud be freezing in a position so they can get the perfect shot that you want. Also whether you want video or stills, black and white or colour (that can be adjusted using photo software), whether the photographer will be using your photos in their portfolio, or whether the only copies will be residing with you, etc
