Football icon set designed

I need a set of 20 (to start with) football badge icons to be designed. They need to be similar to the attached link - but not include the club name and be ever so slightly different to ensure they are not exact copies.

----------

For example, the first icon cannot have the word "CHELSEA" in the image, but must look like it so someone can guess the logo if they knew what it was.

Once these logos have been designed and we are happy with the quality of work, we will be looking to generate a lot more of these logos.
