You are asking a lot for not a lot of money. If you are using your camera to make money, you need to make an investment. Spend $3500-$5000. There is a lot to offer in that price range. The Panasonic AG-AC130a and 160a offer the best bang for the buck with the best warrantee in the industry. In order to make these cameras shoulder mountable, you will need a device such as the DV Multirig.

Your only alternative is JVC HMC600 or 700 series.
