well before you start pitching to anyone you need a business plan.. if you went to any investor they will right away say no if you have nothing but an idea.. you pitch ideas to family and friends for money.. your best bet is to find material on how to start a business where you live and start planning.. cause that is all free plus the cost of some paper and ink.. Your best bet to get good sound advice is contact ths SBA and get andything from them..

once you get all you things in order then comes the hard task of building capital, best way is get some partners.. then pitch to banks, for that matter anyone you know.. try to get loans or see if people are willing to invest in you.. Angel investors are actually a good idea but i would say get to know them first and see whats up with what they want out of it..

I hope i helped, i am a Bus Admin major specializing in entreprenurship so any questions ill try and help..
