i need a graphic designer to create a company logo

i am looking for a graphic designer to create me a logo for my construction company, i have created a design myself to give a bit of an idea of what i am after but i give full creative control over to whoever will be creating the design. i am an australian and i want the logo to have an australian feel to it hence why i have added the southern cross and kangeroo, i will also need the logo to be a vector so i will be able to use it on work uniforms and advertising.
