Two of the biggest things your going to have to contend with is keeping the pigeons in good health and keeping everyone happy.
Think you should from the off make it known what steps your going to take to minimise the risk of infection within the flock, perhaps get the services of a vet and have a screening/testing schedule set in place.
One of the best way of keeping people happy is to keep them well informed, maybe set up a blog and state you'll update it at least once a week.
