I need to have a logo for a phone app as well so perhaps consider that, that could be created in adition

The winner should have some colour in it, that matches our brochures and theme. But I will be looking for something that we (or you) will be able to produce a whole range of logos for different areas. Letter head, a phone icon, a the top right, of the program screens that i uploaded, and to be able to be converted to monochrome if required.
