Convert Image to Logo Files

I already have the artwork that will serve as our company logo—I now need that image professionally prepared so it works everywhere I plan to use it. Please convert the existing file into high-resolution JPEG and transparent-background PNG versions... (Budget: $30 - $250 AUD, Jobs: Adobe Illustrator, Adobe Photoshop, Graphic Design, Illustrator, Image Processing, Logo Design, Photoshop, Vector Design)
