led driver, altium schematic design

I would like a small led driver circuit schematic drawn up in altium designer. It should supply 9 x 5050 warm white led's. It should use easy to find components from digikey or rs-components for example. It can use a dedicated driver, op amp, or whatever is sutable. I would prefer not to use current limiting resistors to burn off power as it is supplied from a battery and should be fairly efficient. It will be run off a single cell li ion battery. Please provide component list and values. Example [login to view URL] [login to view URL] Thankyou for your bids. It is a low budget job of around $30 but it is a great starting point for a first time freelancer. Cheers
