Feedom From Fear; My Latest Idea

Currently I am putting most of my efforts into finding a home to purchase as news of the housing market is very poor, I'm almost afraid to buy at this point.  I still like the idea of selling security and surveillance items via the net and offline as well, security is freedom from fear and that's my latest idea.  I want these items myself, I believe in them and have a real need for them.  I also need specialized cat items such as a special cat door for the patio slider but they are really expensive, about $200.00 I believe I should be able to get them cheaper then that and offer them to people like me who have the need but not that much money.
