I am sorry I am new and I may be asking too much. Me and my Wife are going to start a Restaurant Hardware selling site to sell Restaurant POS hardware with Freely available/Open source Restaurant Point of Sale (To give an example, Floreant POS / http://floreantpos.com and OpenBrravo ( http://openbrravo.com ). My target clients are fine dining and cafe owners. As I have checked its very expensive to give advertisement in Google for "Restaurant" Keyword. There are so many brands and models available that its tough to focus on particular keyword. Anyone can suggest a way would be appreciated.
