Convert drawing (mostly letters) into graphics file for hip-hop artist logo

Hi, Background: I am the owner/founder of a hip-hop record label, and my rapper/lyricist/emcee Yung Stooey is the #1 artist on the label. I need to get one of the drawings his friend did and make it look professional so that we can put it on t-shirts, sweatshirts, etc. As a result, I need a high quality image file to send to the screen printer. 2 steps: 1. Touch up the drawing and make it look better. Right now it looks like a rough drawing. I need someone to make it look professional and smooth. 2. Convert it from JPEG to high resolution image files. Please save a few different image files with different colors and provide me with the Photoshop or Illustrator master file. (Important, the spelling of the name is Yung Stooey . The letter "g" in Stooey is partially a microphone, so you must turn part of the letter 'g' into a microphone like in the drawing!) Thanks!! -Scott
