Displaying satellite data in QGIS to show different colour composite (natural colour, false colour, etc)

I urgently need someone for a GIS work. I'd like to use any multispectral image to display different colour composite in QGIS. This will include natural colour, false color and additional band combinations - such as bands to best see any features (e.g. snow, coal). You will provide me with powerpoint slides that show/teach each step and instructions. Please note that this is very urgent. Only contact me if you are ready to do it now!
