Im sure you get the idea now. You can divide the Ware house and supply meeting rooms. You could have your kitchen certified and have televised banquets. Fund raising will be an ongoing effort for the station, and you will be better off to invite the public there for the fundraisers. Renting your meeting rooms to groups could supply additional income.

Media is expanding really fast with, new low power television stations, more and more cable stations, and the Internet. The internet itself is going to demand more trained techincal help than all the rest put together.

You can prepare your students in all of the necessary fields. The mission statement for your 501c3 will be your starting point, and a guiding statement for your orgainization.
