Convert 50 scanned logos into high quality, printable logos

Over the course of 2 months, I will be sending 50 scanned logos to you. Your job will be to convert these logos into 300 dpi jpg's/TIFF/PSD (4 inches by 4 inches) or Adobe Illustrator files. The final use is for print, so high quality jpg's/TIFF/PSD or Illustrator files are needed. Whatever file format you want is fine, so long as it is print quality. Your bid will be for all 50 file conversions. I need each file back no more than 2 days after I send the file. This is a simple transformation of a SCANNED logo and make it into a black and white .jpg or TIFF file WITH A WHITE or TRANSPARENT BACKGROUND that I can then insert into other documents. Illustrator files are fine as well. These files will end up in InDesign for print purposes, so please keep this in mind. ***Example*** I expect you to take the logo (Cinnabon in this example) and make the edges look sharp, the colors consistent (not 500 different shades of gray), and the overall logo to look as if it were not scanned. Most of the logos I will be sending you will be in better condition (and easier to do) than the Cinnabon logo, but there will be times when you receive a file similar to the Cinnabon in this example. I do **NOT** want the logo to be redesigned or changed in any way. I just want it made high quality for print purposes. Simply take what is there, and make clean it up for high quality print purposes. Please ask any clarification questions as I want to make sure we get the details correct. Thanks, Craig
