436416 Need little graphic work

I had someone do my logo and would like to revise the colors with cmyk colors and have someone make sure the lines are smooth. I think a sloping line has jagged edges. I would also like someone to tweak the colors on the letterhead that was created. This is not a redesign, just recoloring and making current logo look sharper in design for print and web. I want high quality designers who use photoshop. I also need one wordpress header (1000 × 145 pixels) image created. I will be using logo and a design you create by discussing. Worth good review. Do not bid without showing me sample work. Type: "Clean Design" so I know you read this.
