Help me Help The Homeless

Would like to start a mobile food van business selling at events, parks, and local areas. It will be a BBQ style food and would like to donate parts proceeds and food to the homeless people. This a passion of mine to help the needy and hopefully one day be able to put a deposit on a property to accomodate homeless people. In todays society we see a lot of people sleeping in parks, cold hard pavements, streets, or anywhere they can. For some reason this gets to me seeing homeless people especially in very cold winter months sleeping outside or being abused whilst sleeping it rough.
