To implement this feature what I haev done at the moment is I have added a profile property called Share MyShoot, this allows you to select if you have a shoot and are willing to share it, or take people out onto it. This property can then be made public so you can allow others to see it and it will be displayed in your MyShoot profile screen, in the Biography text box in your profile settings screen, you could add the additional rules about getting in contact with you etc.
